Abstract
A flyback switch power supply connects Nheteronymous terminals in a transformer B to a power source, grounds second primary side winding Nheteronymous ends, and ensures that Nand Nare dual-wire parallel windings. Adding a capacitor C, one end of Cis connected to Nhomonymous terminals, and the other end is connected to Nhomonymous terminals. The secondary side winding uses a Qconnection method that is the opposite to the prior art, and is controlled by a PWM signal controlled by another output voltage. The following effect is realized: when Qis connected, Nand Nare both excited, and there is artificial surplus energy; when Qis disconnected, the secondary side Nimplements a rectified output voltage via Qon the basis of the output load requirements, and the leakage inductance and excess energy are non-destructively absorbed by Nvia D
