行波管放大器高壓電源的設計

摘要：文中給出了機載雷達發射機行波管放大器用高壓電源的原理框圖。論述了變換電路通過變壓器的電感和有源開關兩端的電容諧振可以獲得零電壓開關和變壓器鐵芯復位的工作過程。最后給出了高壓電源的實際工作結果。 敘詞：零電壓 諧振 開關 管體 電源 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. Keyword：zero-voltage resonant switch tube-body power supply
