Classification: CPC H  Y | IPC H

Claim 8:
9. A system for power conversion, comprising:
an interleaved resonant power converter including at least a first stage and a second stage; and
a controller configured to:
generate a first pair of complementary signals to drive the first stage,
generate a second pair of complementary signals to drive the second stage,
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, to generate a current-mode control signal based on the current sense signal of the first stage, the controller is further configured to:
generate a feedback voltage based on an output voltage produced by the interleaved resonant power converter, and
pulse the current-mode control signal when a voltage of the current sense signal is equal to the feedback voltage.
