摘要：

Traditional buck DC-DC converter isn't capable of step-up output, even worse it can't be directly reconstructed into single-phase AC-DC converters with unity input power factor. In this paper, based on the analysis of the linear waveform synthesis principle of buck DC-DC converters, double-switch inverter is added on the output side, and a single-phase diode rectifier and an LC filter are added on the input side to obtain a new step-up/down AC-DC converter, which can function as a unity power factor corrector. The theoretical analysis and simulation verification of the step-up/down DC-DC converter and AC-DC converter are carried out. The results show that the two converters have simple control and complete functions, and can he widely applied in the field of AC and DC distribution generation. The conclusions drawn in this paper extends the application area of buck DC-DC converter, which is of academic and applied value.
