Wherein the preset type at least comprises one of the following: three-phase power, single-phase power and DC power. The CT power supply and distribution device is provided with a preset type of power supply by an external power supply. Alternatively, if the preset type of power source includes a three-phase power source, a single-phase power source, and a direct current power source, the power source adaptation terminal 2 includes a three-phase power source terminal, a single-phase power source terminal, and a direct current power source terminal corresponding to the preset type of power source voltage. The preset type of power source may also include a three-phase power source, a single-phase power source, and other types of power sources other than a direct current power source, which are not limited herein.
The power distribution module 1 can convert and output power supply voltage while keeping the type of external power supply unchanged, for example, the power distribution module 1 can convert alternating current of a first voltage into alternating current of a second voltage and output the alternating current to the CT device 4; the power distribution module 1 may also change the power supply type at the same time as converting the voltage, for example to achieve a conversion between an alternating voltage and a direct voltage.

Illustratively, the energy management module 3 detects the type of power received by the power adapter terminal 2, the power voltage, and switches the operating state of the power distribution module 1 according to the type of power received by the power adapter terminal 2, the power voltage. Illustratively, when the preset type of power supply voltage meets the low power load power supply requirement in the CT apparatus 4, the energy management module 3 directly inputs the preset type of power supply voltage to the CT apparatus 4, and the power distribution module 1 does not convert the voltage.

Meanwhile, the power supply and distribution device of the CT equipment 4 comprising the energy conversion module is also characterized by high integration through the integrated design of the energy conversion module. Compared with the traditional CT power supply and distribution system, the CT power supply and distribution device in the embodiment can reduce the use amount of component-level cables and system-level cables, reduce the material cost, further improve the integrality of the power supply and distribution system and reduce the total space occupation of the power supply and distribution system on a hospital field by reducing the wire diameter of the system power supply cable. In addition, the CT power supply and distribution equipment in the conventional technology only supports three-phase alternating current input, and in this embodiment, the plurality of power supply adapter terminals 2 receive external power, so that the voltage input range supported by CT power supply and distribution and the supported electric energy types are enlarged.
On the basis of the connection structure of the power distribution module 1 and the power supply adapter terminal 2 in the present embodiment, the following embodiment describes units that may be included in the power distribution module 1.
In some of these embodiments, the power distribution module 1 includes an energy conversion module 10. The energy conversion module 10 comprises a rectifying unit 11 and an energy conversion unit 12, wherein one end of the rectifying unit 11 is connected with the plurality of power supply adaptive terminals 2, the other end of the rectifying unit 11 is connected with one end of the energy conversion unit 12, and the other end of the energy conversion unit 12 is connected with the CT equipment 4; wherein, the rectifying unit 11 is used for converting alternating current into direct current; and an energy conversion unit 12 for adjusting the voltage of the direct current. If the preset voltage includes single-phase alternating current, the rectifying unit 11 may implement single-phase alternating current rectification; if the preset voltage includes three-phase alternating current, the rectifying unit 11 may implement three-phase alternating current rectification. The energy transforming unit 12 may be used to transform the electric energy voltage output from the rectifying unit 11 into a voltage required for the operation of the CT apparatus 4. Taking the energy conversion unit 12 as an example of power supply of the main loop where the medium voltage generator and the bulb tube are positioned in the CT equipment 4, the energy conversion unit 12 can output kilovolt direct current, thereby reducing the energy conversion burden of the high voltage generator in the CT equipment 4 and achieving the effects of reducing the power transmission burden of the CT slip ring system and reducing the occupation of the rotor side space of the CT. If the CT power supply and distribution device further includes an energy storage module 13, the energy conversion unit 12 may be further configured to convert the electric energy voltage output by the rectifying unit 11 into a voltage required by the energy storage module 13 for energy storage.
Alternatively, the energy transforming unit 12 comprises a bi-directional DC/DC converter.

When the external power supply outputs three-phase alternating current, the bridge arm group 1, the bridge arm group 2 and the bridge arm group 3 form a three-phase alternating current rectifying circuit so as to carry out three-phase bridge rectification. When the external power supply outputs single-phase alternating current, any one of the bridge arm groups 1, 2 and 3 and the bridge arm group 4 form a single-phase alternating current rectifying circuit to carry out single-phase bridge rectification. The inductor and the DC bus capacitor form a DC bus filter, and the rectified DC voltage waveform is subjected to smooth conditioning and EMI (Electromagnetic INTERFERENCE EMI FILTERING) filtering. When the external power supply outputs direct current, the direct current is directly input to the energy conversion unit to regulate the voltage level so as to output power to the CT equipment and/or store energy to charge the energy storage module.

The energy management module 3 further includes a voltage and current sensing probe, and the energy management module 3 controls the rectifying unit 11 to perform ac-dc rectification, dc-dc rectification or not to perform rectification by controlling on-off of the S1 and S2.
When the controller unit 31 in the energy management module 3 judges that the external power supply inputs three-phase alternating current (such as 380Vac, 400Vac three-phase alternating current and the like) according to the voltage and current sensing probe signals, the controller unit 31 issues a command to an alternating current-direct current rectifier in the rectifying unit 11 to execute three-phase rectifying and filtering operation, and at the moment, a three-phase alternating current rectifying circuit formed by the bridge arm group 1, the bridge arm group 2 and the bridge arm group 3 carries out bridge rectification to provide electric energy input for the CT equipment 4 system;
When the controller unit 31 determines that the external power source inputs single-phase ac power (such as single-phase ac power of 220Vac, 230Vac or 110 Vac) according to the voltage and current sensing probe signal, the single-phase ac terminal L is connected to the live wire port of the mains socket, and any one of the terminals U, V, W is connected to the neutral wire port of the mains socket, so as to form a loop for receiving the single-phase ac power of the mains. The controller unit 31 issues a command to close the command control switch S1 and issues a command to the ac/dc rectifier in the rectifying unit 11 to perform single-phase rectification, and at this time, any one of the bridge arm groups 1, 2, 3 and 4 forms a single-phase ac rectifying circuit to provide electric energy input for the CT device 4 system
When the controller unit 31 determines that the external power input is direct current according to the voltage and current sensing probe signal, the controller unit 31 issues a command to control the ac/dc rectifier in the rectifying unit 11 not to start running and control the switch S2 to be closed, the direct current is input to the dc-dc converter in the power distribution module 1, and the direct current is output to provide electric energy input for the CT equipment 4 system through electric energy voltage regulation and conversion.
The user may use one of the three power adapter terminals 2 depending on the actual field power socket type. The CT system device may then detect the type of voltage input via sensor set 14 to automatically select the adapter circuit to provide power input to CT device 4.
