[0005] Disadvantages of the prior art: when the structure shown in Fig. 1 is used for a high-voltage pulse power supply, it can meet the requirements of the electronic cyclotron system for a high-voltage pulse power supply in nuclear fusion experiments, but there are also the following disadvantages: (1) the power module outputs lower voltage level
Since each module adopts an isolated input method, this will increase the number of secondary windings, increasing the cost and installation space of the transformer

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific examples.

[0020] The present invention is used for the power supply module unit topological structure wiring mode of the high-voltage pulse power supply such as figure 2 , image 3 , Figure 4 , Figure 5 shown. in figure 2 , image 3 with Figure 4 , Figure 5 For the same topology, the difference is the wiring method. Both wiring methods have advantages and disadvantages. figure 2 In the wiring mode shown, if the midpoint of the two series capacitors C1 and C2 is connected to the neutral line of the transformer, the unit’s requirements for midpoint balance control will be reduced, but the cost of the transformer will be increased; image 3 In the wiring method shown, the transformer does not have a neutral wire, so the power supply unit will have high requirements on the neutral point balance control, which will undoubtedly increase the comple...

Abstract

The present invention belongs to a power module, and especially relates to a submodule for a high-voltage long-pulse PSM power source. The submodule for a high-voltage long-pulse PSM power source is formed by a three-phase diode rectifier bridge, a bus capacitor, a switch tube and a fly-wheel diode, wherein the two input ends of the diode rectifier bridge are connected with a peripheral circuit, asecondary winding is connected with the two inter-bridge positions of the diode rectifier bridge, and the peripheral circuit is formed by a bus capacitor, a switch tube and a fly-wheel diode. The power module is high in level of the output voltage so that the required number of the modules is small in a condition of the same voltage output. The module input is a single-phase alternating current mode, generally, the secondary winding has three phases which can be decomposed into input of three same modules to reduce the volume of a transformer and improve the output voltage level so as to improve the power density of the whole machine.

Description

technical field [0001] The invention belongs to a power supply module, in particular to a submodule used for a high-voltage long-pulse PSM power supply. Background technique [0002] In the tokamak device (HL-2A), in order to make the plasma temperature reach the 10keV level required for the fusion reaction, in addition to the traditional ohmic heating, auxiliary heating must be used. As one of the most important systems of the tokamak device, the auxiliary heating system has always been the key development object in various international devices. Auxiliary heating mainly includes neutral beam injection (NBI) and radio frequency wave heating (RF). Among them, radio frequency wave heating mainly includes electron cyclotron resonance heating (ECRH) in the millimeter wave band, low hybrid wave heating (LHH) in the centimeter wave band, and There are three forms of ion cyclotron resonance heating (ICRH) in the meter band. Compared with the other two wave heating methods, elect...
