| Abstract: | This paper analyzes the defects of traditional high-voltage switching mode power supply and proposes a revised starting circuit based on SG3525 for onboard high voltage switching mode power supply. Experimental results show that this revised starting circuit sucessfully solves the high power consumption problems derived from tranditional starting methods. In addtion, this new starting circuit has self-starting function and provides a more universal way of circuit design for high voltage switching mode power supply. |
