<p>A primary resonant inductor (Lr) and a primary resonant capacitor (Cr) form a primary resonant circuit, and secondary resonant inductors (Ls1, Ls2) and secondary resonant capacitors (Cs1, Cs2) form a secondary resonant circuit. Equivalent mutual inductances (Lms1, Lms2) are formed between a primary winding (np) and secondary windings (ns1, ns2) by magnetic resonance coupling, and the primary and secondary circuits form a multi-resonant circuit containing at least two LC resonant circuits. Power is transferred from the primary circuit to the secondary circuit. Resonance energy that is not transmitted from the primary winding is retained in the multi-resonant circuit, as is resonance energy that is received by the secondary windings but not supplied as output. In particular, on the secondary side, resonance energy is retained in a current path in which rectification elements are not arranged in series.</p> |
