Abstract:
1. A resonant converter comprising: a transformer with a primary winding and at least two secondary windings of different winding directions; a capacitive element in series with the primary winding; at least one external inductive element in series with the capacitive element and the primary winding; an inverter in series with the capacitive element, the external inductive element, and the primary winding of the transformer; and multiple outputs coupled to the secondary windings of the transformer; wherein the resonant frequency of the resonant converter is determined by the main inductance and the leakage inductances of the transformer, the capacitive element, and the external inductive element, and wherein different ratios of a magnitude of output voltage to number of turns are provided in respect of associated secondary windings having different winding directions.
