Abstract:The principle of high-voltage power supply of travel-wave-tube amplifier for airborn transmitter is given in this paper.Zero-voltage switching for active switch and transformer-core resetting are achieved from the resonant that occurs between the capacitance across the active switch and the transformer inductance.The experiments of high-voltage power supply are given.
