Implementación de un Sistema de Standby en un Elevador con Corrección del Factor de Potencia

Abstract

Power supplies for household appliances have to comply with strict standby regulation. This work analyzes different options for implementing a low power consumption standby mode on a Power Factor Correction (PFC) Continuous Conduction Mode (CCM) Boost Converter with multiplier based control. This topology is especially troublesome because of the high amount of resistive sensors connected to high voltage nodes. A cheap, simple standby circuit is designed and tested on a commercial, low cost, 100 W switching mode power supply (SMPS). The active power consumption of the converter while on standby is always under 0.5 W for any AC input voltage within universal range, complying with European Ecodesign Regulations.
