Abstract
The present invention provides a switching power supply capable of limiting power supply output power with a method compatible with reduced size regardless of the modulation system. The present invention is able to provide a compact switching power supply that enables the amount of limitation of power supply output power to be regulated as desired with little inrush current and overshoot particularly in the case of adapting to power supply soft starting by providing a reset device between a switching signal generation device and switching element, applying a reset pulse signal to reset device, and changing the duty of the above reset pulse signal between 0% and 100%.
