STAND-BY POWER CONTROL CIRCUIT

摘要

PURPOSE: A standby power control system is provided to reduce the cost and energy substantially by reducing the amount of energy consumption economically. CONSTITUTION: The PWM controllers have direct self-supply function of generating the operation power needed for basic process from the high voltage direct link. The direct self-supply function generates the driving energy of a converter without the help of outside. An auxiliary converter minimizes the power loss by shutting the operation power of the main converter and the auxiliary circuit in standby mode of SMPS.
