More Information
Summary:The invention discloses a mixed-mode active clamping power converter, and the power converter comprises an input inductor, a low bridge switch, an upper bridge switch, a first energy storage capacitor, a clamping capacitor, a resonance inductor, an excitation inductor, a transformer, an output diode, and an output capacitor. The input inductor is provided with a boundary inductance value, and an input power source operates between a first voltage and a second voltage. Moreover, the boundary inductance value is set according to the first voltage and a load, so as to serve as an initial condition for the converter, thereby enabling the input inductor to be operated in a boundary conduction mode. The converter improves the power conversion efficiency.
