[Abstract]:As an important microwave signal amplifying device, gyrotron has many advantages, such as high power, wide bandwidth and high gain, and has great development potential and application prospect, which makes it a priority choice of millimeter wave coherent radiation source. Mainly used in high power millimeter wave radar, high power microwave weapons, early warning, electronic warfare, controlled thermonuclear fusion and other microwave fields. Therefore, it is very important to study its power supply system-high-power high-voltage pulse power supply. The traditional high-power high-voltage pulse power supply is a linear power supply, which has the advantages of large volume, heavy weight, low efficiency and serious heating. Compared with linear power supply, phase shift control full-bridge soft switching technology is used to design high-power high-voltage pulse power supply. The parameters are output voltage 60kV, output current 1.5A, pulse frequency 200Hz, pulse width 50 渭 s. It realizes the zero voltage switching on of the switch tube, reduces the switching loss of the switch tube, improves the efficiency of the power supply, and makes it the first choice of the working power supply for the gyrotron. In this paper, the main circuit topology of the high power high voltage pulse power supply is full-bridge converter, the phase-shifted resonant control chip UC3875 as the main control chip, and the 2SD315AI as the switch tube drive chip to design. This power supply realizes the zero voltage switching of the switch tube and has the functions of under-voltage, over-current, short-circuit protection and extremely high working efficiency. The main work of this paper: 1. The main circuit of power supply is designed. According to the design index of power supply, the parameters of components are calculated and the model of components is selected. The simulation results are observed and analyzed by Pspice software. 2. The drive circuit of insulated gate bipolar transistor (insulated gate bipolar transistor,IGBT) is designed by using 2SD315AI chip, its driving waveform is tested, and the undervoltage, over-current and short-circuit protection functions are verified by experiments. The high frequency transformer is designed by the method of area product of magnetic core (AP method). The design flow is as follows: (1) selecting the core material and model; (2) calculating the window area and effective cross section area of the core; (3) calculating the turns of the primary winding and the secondary winding; (4) calculating the wire diameter of the primary secondary winding conductor. A high voltage modulator is designed, which is composed of several IGBT series, the driving signal of IGBT is generated by half bridge circuit, and the output is coupled with magnetic loop, which isolates the multi-group driving signal and ensures the consistency of the multi-group driving signal. The high power and high voltage pulse power supply designed in this paper has the advantages of low switching loss, high efficiency, light weight, small volume, adjustable output voltage, good stability and easy control.
