[0002] The subject of this invention is not only the equipment itself, but also the totality of elements that it features with the purpose of providing it with the characteristics that have been described in the first claim. [0003] This invention is characterizes by the possibility that it offers of being able :o use the equipment independently of the supply voltage, it: being unnecessary to make any structural change, since the machine automatically detects the input voltage and acts so that the actual equipment ana the rest of the elements or auxiliary apparatus connected to the apparatus can work properly without it being necessary to make any change in the connection of the equipment supply. [0004] The present invention is also characterized by the possibility of acting on the manner and conditions in which the supply of input current is carried out. [0005] Therefore, the present invention is encompassed within the field of equipment used in radiography. BACKGROUND OF THE INVENTION [0006] Until the present time equipment used in radiography has the drawback of operating at different supply voltages, especially as regards auxiliary equipment connected to it, such as, for example, collimators, ionisation chambers, brakes etc. This equipment is supplied using transformers or autotransformers with a series of selectable outlets, that, depending on the input voltage, some or others are selected. This obliges a manual change to be made at the moment of setting-up, depending on the input voltage. An action that is only carried out on connecting the equipment to the supply if the supply voltage is not. correct it car. damage saio equipment not connected to the appropriate supply voltage. [0007] On the other hand, it also happens that in certain installations, depending on the quality of the electrical supply, it can happen that a dip in the supply from the network takes place, due to the demand of the X-ray equipment, because of which the use of said apparatus becomes incompatible with the supply that there is in the area. [0008] It also occurs that some X-ray equipment is not equipped with the necessary electronics for its operation at voltages different to those for which it has been designed. [0009] Therefore the purpose of the present invention is that of developing X-ray equipment that allows its use independently of the supply voltage and frequency, where it is not necessary to carry out any change-over or selection action of the appropriate outlet of the auto-transformer for the supply of auxiliary equipment, depending or the supply voltage of the equipment, and where, furthermore, with the purpose of avoiding the dip in the network supply, in be possible to program the current so that it be adaptec to the characteristics of the service. DESCRIPTION OF THE INVENTION [0010] The proposed invention of X-ray equipment allows radiography activities to be carried out independently of the input voltage and frequency, being valid for a range of 90 to 264 V of alternating current, as well as for 50 or 60 Hz. [0011] The equipment has a Buck-boost type controlled converter, connected to a bank of capacitors, which are charged at a fixed voltage, independently of the supply voltage. At the outlet of the bank of capacitors a controlled power inverter is placed, in whose outlet a step-up transformer, which is connected directly with the X-ray tube, is placed. [0012] The converter allows the charging of the bank of capacitors to be carried out in a controlled manner, by means of an input current programmer, which avoids dips in the networks in areas that are less interconnected or directly supplied through independent supply sets. Furthermore, and thanks to the fact of allowing the charging of the bank of capacitors to be carried out in a controlled manner, the overload of the network supply connection is avoided, both in the actual cable and in the socket. [0013] Furthermore, the equipment has a network voltage control unit, governed oy means of a microprocessor, which carries out both evaluation of the input voltage and determined actions, which for a given supply voltage activates solid state relays corresponding to the correct supply input of the auto-transformer, with the purpose of obtaining the most suitable supply for the different auxiliary equipment, such as brakes, collimators, or ionisation chambers. DESCRIPTION OF THE DRAWINGS [0014] To supplement the description that made herein, and with the aim of leading to a better understanding of its characteristics, this specification is accompanied by a set of drawings in whose figures, in an illustrative and non-limiting way, the most significant details of the invention have been represented. Figure 1. Shows a representation of the different clocks that form the X-ray equipment that is the subject of the invention. PREFERRED EMBODIMENT OF THE INVENTION [0015] In view of the figures mentioned a method of preferable embodiment of the invention is described below, as well as an explanation of the drawings. [0016] In figure 1 we can see that the supply voltage (1) of the equipment comes both to an AC-DC universal voltage source (8), as well as to a controlled current converter ,21, and to input voltage control equipment (9).

[0002] The subject of this invention is not only the equipment
itself, but also the totality of elements that it features
with the purpose of providing it with the characteristics that
have been described in the first claim.
[0003] This invention is characterizes by the possibility that
it offers of being able :o use the equipment independently of
the supply voltage, it: being unnecessary to make any
structural change, since the machine automatically detects the
input voltage and acts so that the actual equipment ana the
rest of the elements or auxiliary apparatus connected to the
apparatus can work properly without it being necessary to make
any change in the connection of the equipment supply.
[0004] The present invention is also characterized by the
possibility of acting on the manner and conditions in which
the supply of input current is carried out.
[0005] Therefore, the present invention is encompassed within
the field of equipment used in radiography.
BACKGROUND OF THE INVENTION
[0006] Until the present time equipment used in radiography

has the drawback of operating at different supply voltages,
especially as regards auxiliary equipment connected to it,
such as, for example, collimators, ionisation chambers, brakes
etc. This equipment is supplied using transformers or
autotransformers with a series of selectable outlets, that,
depending on the input voltage, some or others are selected.
This obliges a manual change to be made at the moment of
setting-up, depending on the input voltage. An action that is
only carried out on connecting the equipment to the supply if
the supply voltage is not. correct it car. damage saio equipment
not connected to the appropriate supply voltage.
[0007] On the other hand, it also happens that in certain
installations, depending on the quality of the electrical
supply, it can happen that a dip in the supply from the
network takes place, due to the demand of the X-ray equipment,
because of which the use of said apparatus becomes
incompatible with the supply that there is in the area.
[0008] It also occurs that some X-ray equipment is not
equipped with the necessary electronics for its operation at
voltages different to those for which it has been designed.
[0009] Therefore the purpose of the present invention is that
of developing X-ray equipment that allows its use
independently of the supply voltage and frequency, where it is
not necessary to carry out any change-over or selection action
of the appropriate outlet of the auto-transformer for the
supply of auxiliary equipment, depending or the supply voltage
of the equipment, and where, furthermore, with the purpose of
avoiding the dip in the network supply, in be possible to
program the current so that it be adaptec to the
characteristics of the service.

DESCRIPTION OF THE INVENTION
[0010] The proposed invention of X-ray equipment allows
radiography activities to be carried out independently of the
input voltage and frequency, being valid for a range of 90 to
264 V of alternating current, as well as for 50 or 60 Hz.
[0011] The equipment has a Buck-boost type controlled
converter, connected to a bank of capacitors, which are
charged at a fixed voltage, independently of the supply
voltage. At the outlet of the bank of capacitors a controlled
power inverter is placed, in whose outlet a step-up
transformer, which is connected directly with the X-ray tube,
is placed.
[0012] The converter allows the charging of the bank of
capacitors to be carried out in a controlled manner, by means
of an input current programmer, which avoids dips in the
networks in areas that are less interconnected or directly
supplied through independent supply sets. Furthermore, and
thanks to the fact of allowing the charging of the bank of
capacitors to be carried out in a controlled manner, the
overload of the network supply connection is avoided, both in
the actual cable and in the socket.
[0013] Furthermore, the equipment has a network voltage
control unit, governed oy means of a microprocessor, which
carries out both evaluation of the input voltage and
determined actions, which for a given supply voltage activates
solid state relays corresponding to the correct supply input
of the auto-transformer, with the purpose of obtaining the
most suitable supply for the different auxiliary equipment,
such as brakes, collimators, or ionisation chambers.

with the aim of leading to a better understanding of its
characteristics, this specification is accompanied by a set of
drawings in whose figures, in an illustrative and non-limiting
way, the most significant details of the invention have been

Figure 1. Shows a representation of the different clocks that
form the X-ray equipment that is the subject of the invention.
PREFERRED EMBODIMENT OF THE INVENTION
[0015] In view of the figures mentioned a method of preferable

(14), collimators (15) and ionisation chambers (16) are
supplied at the proper voltage.

[0018] The X-ray equipment has a controlled current (2)
converter, on which an input current programmer (3) acts, so
that the charging of the bank of capacitors (4) can be
programmed, fairly rapidly, with the purpose of avoiding a dip
in the distribution network, due to lack of generation; and
also that the overload of the connection point to the supply
network is avoided.
[0019] The controlled current converter (2) allows the Dank of
capacitors to be charged at a fixed vcltage and independent of
the supply voltage, the vcltage to which the X-ray equipment
is connected not mattering in any way. To said bank of
capacitors (4) a power inverter (5) is connected, whose outlet
is connected to a step-up transformer (6), these latter being
governed by a control (11). The X-ray tube (7) is connected to
the set-up transformer (6).
