Paper Abstract

The damage capacity of weapon systems is enhanced when all-electronic safety and arming device (ESAD) is applied, so that ESAD has been favored by the military power. ESAD must ensure the normal work in the stipulation of -40 °C ~ +60°C temperature. When high voltage pulse power supply of piezoelectric transformer (PT) is used in ESAD the charging time has the large dispersion and affects the striking capability of weapon systems. In order to control the inconsistency charging time due to environment temperature change the adaptive frequency tracking control system for high-voltage pulse power supply of PT is designed. Theoretical calculation of current lag angle under zero voltage switching condition for resonant current is derived. Sampling circuit and control circuit are designed by applying the phase-locked loop (PLL) control technology. Experiment results have proved that this control can ensure the consistency of converter output under different environment.
