Classification: CPC H  Y | IPC H

Claim 15:
16. An apparatus for power conversion, comprising:
a controller configured to:
generate a first pair of complementary signals to drive a first stage of an interleaved resonant power converter;
generate a second pair of complementary signals to drive a second stage of an interleaved resonant power converter;
generate a current-mode control signal based on a current sense signal of the first stage;
adjust a switching frequency of the first pair of complementary signals based on the current-mode control signal; and
adjust a switching frequency of the second pair of complementary signals to match the switching frequency of the first pair of complementary signals,
wherein generating the current mode control signal comprises:
generating a feedback voltage based on an output voltage produced by the interleaved resonant power converter, and
pulsing the current-mode control signal when a voltage of the current sense signal is equal to the feedback voltage.
