Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 入力電源電圧が所定値以上となったときに、 制御回路部への電源供給を停止し、制御回路部への供給 電圧が入力電源電圧の値の大小にかかわらず、常に一定 電圧で動作する。 【構成】 入力電源1と、少なくとも1つの高速スイッ チング動作を行うスイッチング素子及びインダクタ,コ ンデンサなどで構成される電源主回路部2と、その電源 主回路部2のスイッチング素子を制御する制御回路部3 とで構成される電源装置において、入力電源電圧が所定 値以上となったときに、制御回路部3への電源供給を停 止する機能を有する保護装置8を、その制御回路部3の 直前に具備している。 (57) [Summary] [Purpose] When the input power supply voltage exceeds a specified value, The power supply to the control circuit unit is stopped, and the control circuit unit always operates at a constant voltage regardless of the magnitude of the input power supply voltage. [Structure] An input power supply 1, a power supply main circuit unit 2 including at least one switching element that performs high-speed switching operation, an inductor, a capacitor, and the like, and a control circuit unit 3 that controls the switching elements of the power supply main circuit unit 2. In the power supply device configured by, a protection device 8 having a function of stopping the power supply to the control circuit unit 3 when the input power supply voltage exceeds a predetermined value is provided immediately before the control circuit unit 3. is doing.
