[0056] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0057] figure 1 A schematic diagram of the hardware connection of the present invention. The converter includes a transformer T, a power switch Sn, an LC filter network 101, a resistance feedback network 102, a current detection unit 103, an error amplifier and frequency compensation circuit 104, and a PWM modulator 105 for control and drive Circuit 106. The power switch Sn is connected to the input power terminal and the logic control and driving circuit 106, the output of the transformer T is connected to the LC filter network 101, and the input is connected to the input power terminal. The LC filter network 101 has an output terminal connected to a resistance feedback network 102 and a current detection unit 103 respectively. The input terminals of the error amplifier (EA) and the frequency compensation module are respectively connected with the output of t...
