Claim 14:
15. A method comprising:
receiving an input power at a first converter and at a second converter;
generating an output power as an interleaved output of the first converter and the second converter;
generating a first drive signal to control switching of the first converter;
receiving a first cycle signal from the first converter;
receiving a second cycle signal from the second converter, wherein the first and the second cycle signals have a power phase time corresponding to a power phase of a respective converter and a ringing phase time corresponding to a ringing phase of the respective converter;
determining a master ringing phase time of the first cycle signal;
applying the master ringing phase time to the second cycle signal to determine a slave ringing phase time; and
generating a second drive signal to control switching of the second converter in accordance with the slave ringing phase time.
