Power converter and method of stabling voltage gain
A power converter includes a primary side compensation capacitor, a transformer and a secondary side compensation capacitor. The primary side compensation capacitor receives a first AC voltage from a first switch circuit. The transformer receives the first AC voltage to generate a second AC voltage. The secondary side compensation capacitor transfers the second AC voltage to a second switch circuit to generate a DC output voltage. The operating frequency of the first switch circuit is set within the 0.8*fa to 1.2*fb, and fb is at most 1.5 times of fa. The primary side compensation capacitor and a primary side leakage inductance of the transformer correspond to a first resonant frequency, the secondary side compensation capacitor and a secondary side leakage inductance of the transformer correspond to a second resonant frequency, fa and fb are the lower one and the higher one of the first and second resonant frequency respectively.
