PURPOSE:To convert power with high efficiency by a small-sized circuit, and to improve the degree of freedom of the design of a rectifier simultaneously. CONSTITUTION:AC input currents are positioned at an Ii (l) and the output voltage of DCs at an Eo (7). A pure resistor RL (6) is used as load, and a Co (5) represents an output smoothing capacitor having sufficient magnitude. A diode D (4) and a parallel capacitor Cd (3) containing diode capacity are mounted, and the resonance of auxiliary resonance frequency is generated by the capacitor Cd and an inductor L (2), thus resulting in the soft switching of the voltage waveform of the diode. |
