Abstract: Aiming at the problem that load discharge characteristics of ionic wind air accelerator are affected by tiny fluctuations of the voltage, a special highvoltage power supply was designed. The main control circuit, the driving circuit and the protecting circuit for power metal oxide semiconductor field effect transistor(MOSFET), the sample feedback circuit, the circuit for highvoltage boost and the multiple times for the voltage and rectifier circuit were included in the hardware circuits design of the high voltage power supply. The system configuration of master chip PIC, the setting for the duty cycle and frequency of pulse width modulation(PWM) and the flow chart of main program and interrupt program were included in the software designs. The high voltage power supply was evaluated by the simulation by Multisim10 software and the experiment of prototype debugging. The results indicate that the designed power supply with tiny fluctuations of the voltage is achieved, which is as the power module for followup researching of ionic wind air speeding.
