Abstract

Abstract: In order to meet some special area wide input voltage range requirements of the home appliance controller, through using the auxiliary power of the flyback switching power supply to over voltage detection circuitry. Design a low standby power flyback switching power supply with input range of 70VAC~300VAC, The test result shows that when the input voltage range is 70VAC~300VAC, the two circuit output voltage fluctuation can be controlled within 2%, the ripple can be controlled at 100mV, and the noise can be controlled at 200mV. And the whole control system standby power can be reduced by about 0.3W, the facts show that the design is feasible and effective.

Key words: Home appliance, Wide range, Low power consumption, Zero-Cross, Flyback switching power
