Design Of The High Voltage Pulse Power Supply Base On The Ac/dc Superimposed Technology

The conventional high-voltage pulse power supply generally based on rectifier circuit and frequency transformer, then used the rotary spark gap switches or magnetic compression switch for high-voltage pulse. Such power supplies not only more costly, but also difficult to control, access to the pulse frequency range is limited and inefficient. In a large number of referencing and research-related information, the paper discussed the AC/DC high-voltage pulse power superimposed pulse theory, the implementation. Grasp the high pressure pulse power of main circuit design and control mechanism, Using the MATLAB tool simulated the high-voltage pulse power supply circuit , from the results of simulation, the design of high-voltage pulse power supply generated the voltage waveform is single , stability, wide frequency range and efficient. Moreover, high-voltage pulse power supply for the future of the actual design of the full theory.This design of high-voltage pulse power supply includes main circuit and control circuit. Main circuit including AC and DC power. The AC power supply using IGBT as a pulse compression system and full-bridge inverter circuit control switch. Using Beijing Fall on the source company's TX-DA962A-drive modular design of the drive circuit, and design the corresponding buffer circuit. DC power based on Johnson-type DC-DC converter and voltage doubler circuit. Components on the circuit parameters in a detailed calculation.Power control system based on DSP , TI produced TMS320F2812 chip as a PWM control unit, and capture voltage and current feedback control. Describes the control system hardware design and software design, including the power supply circuit, reset circuit, PWM generation circuit and the A / D uses a subroutine, PWM subroutine and other designs.The simulation results verify the design of this high-voltage pulse power supply is correct and effective.
