Title:
POWER SUPPLY START SYSTEM
Document Type and Number:
WIPO Patent Application WO/2002/019506
Kind Code:
A1
Abstract:
A power supply start system for eliminating a start failure occurring at a simultaneous start and improving quality and reliability. A voltage converters (11-1), (11-2) transform input reference voltages and feed the transformed voltages to load elements. A simultaneous start signal generation means (21) generates simultaneous start signals (K1) for simultaneously starting the voltage converters (11-1), (11-2). A potential difference detection means (22) detects the potential difference between input reference voltages. A forced start means (23) invalidates the simultaneous start signals (K1) when a potential difference is detected, and forcibly starts the voltage converters (11-1), (11-2) after the potential difference is eliminated.
