Classification: CPC H  Y | IPC H

Claim 19:
20. 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 adjusting the switching frequency of the first pair of complementary signals comprises:
starting to increment a counter when the counter is equal to zero,
switching values of the first pair of complementary signals when the current-mode control signal pulses,
starting to decrement the counter when the current-mode control signal pulses, and
switching the values of the first pair of complementary signals when the counter is equal to zero.
