Abstract :
In order to adapt the miniaturization and low EMI of pulsed power supply, a novel quasi-resonant piezoelectric transformer converter for high voltage pulse capacitor charging was developed. The system has the advantages of simple structure, absorbing the switch capacitive parameters and zero voltage switching (ZVS). Therefore, this converter is suit to operate under high-frequency conditions. The working principle of converter was introduced briefly, the working modes of inverter were analyzed and the formula calculating the resonant inductive and switch frequency was listed. At last, the design instance was described, the result of reality and calculated were well consistent.
