Series Switching Power Supply with Wide Input Voltage Based on Dual-Loop Control

Abstract:

The circuit of series switching power supply based on voltage and current dual-loop control is proposed, which can work in the voltage range from 12V to 90V. It is less influence to working state when capacitive load is accessed. The circuit have the function of quickly response, short circuit protection and overcurrent protection. The power supply have advantages of low-cost and working stability, which can be used to different various industry alarms and blasting signal lights in the wide voltage range.
