Design of Micro Power Consumption Synchronous Chopped Wave Power Supply Based on Fixed and Mobile Double Comparative Point

Abstract:

This paper proposes a design method of the micro power consumption synchronous chopped wave and low-power switching power supply based on fixed and mobile double comparative point. The output of this power supply ranges from 5V to 200V. It overcomes the residual voltage effect after the bridge rectifier by using fixed comparative point to limit the maximum output voltage, and stabilizes the voltage by using mobile point to produce the required output voltage. The circuit charges with nonlinear resistors pattern in the low voltage, thus improving the charging efficiency, and it has short circuit protection function, simple structure and low power consumption.
