摘要:This paper designs a high voltage DC power supply with wide-range output voltage up to 35kV for electrostatic applications. The proposed system is composed of a boost power factor correction converter for improving input power factor, a voltage source full bridge inverter with series parallel resonant control, a high voltage high frequency transformer with special design to decrease the power loss, and a high voltage high frequency rectifier unit for producing 35kV high voltage output. The mathematical models of series parallel resonant inverter have been described. The duty cycle of the boost converter is utilized as actuating variables to cope with the regulations of DC bus voltage. Operating principles and design considerations of the high-voltage power supply are discussed and analyzed. Furthermore, the control of PFC converter and full bridge converter is achieved based on dsPIC DSC microcontroller. Finally, a laboratory prototype is implemented and tested to verify the feasibility of the proposed structure.
