| Abstract: | Aimed at the problems that the output voltage ripple is larger when DC/DC switching power supply high voltage output,a design method and test result of a ±50 V dual-output DC/DC switching power are introduced.This circuit uses PWM control chip,which works in flyback mode.The input and output achieve isolation through the optocoupler.The converter features high load capacity,low ripple,high output voltage,and it can provide a stable supply voltage for electronic equipment. |
