Abstract
A switching power supply circuit can include: an energy storage capacitor; a high-frequency switching network coupled to the energy storage capacitor, and being configured to receive a low-frequency AC input voltage, to charge the energy storage capacitor, to perform high-frequency chopping on the low-frequency AC input voltage and/or a voltage of the energy storage capacitor, and to generate a high-frequency AC signal; and a rectifier module coupled to the high-frequency switching network, and being configured to receive the high-frequency AC signal, to rectify the high-frequency AC signal, and to generate a DC signal.
