[0018] In order to describe the technical solution of the present invention more clearly and completely, the present invention will be further described below in conjunction with the accompanying drawings.
[0019] Please refer to figure 1 , the present invention proposes a forward-flyback dual-circuit balanced load switching power supply circuit, the forward-flyback dual-circuit balanced load switching power supply circuit includes: an input terminal, a first transformer T1, a second transformer T2, and a dual-channel output terminal. The first transformer T1 and the second transformer T2 convert the input direct current at the input terminal into alternating current and output it to the dual output terminals, the primary winding of the first transformer T1 is connected to the input terminal, and the first transformer T1 The primary winding of T1 is connected in series with the primary winding of the second transformer T2, and the secondary winding of the first transformer T1...
