Abstract :
A multilayer-winding transformer made of a planar conductor and insulator has a small leakage inductance and a large winding capacitance between the terminals. This winding capacitance causes an undesirable oscillation in the conventional voltage resonant buck-boost converter. A novel type of voltage resonant buck-boost converter which has the resonant inductor in the secondary side of the transformer is presented. This converter can utilize the winding capacitance as part of the resonant capacitor without making the operation complex
