1. A resonant power converter system, comprising:
a plurality of resonant converters connected in parallel; and
an output voltage regulator configured to generate a common control reference voltage or current signal provided to each of the plurality of resonant converters, the common control reference voltage or current signal based at least in part upon a signal from a single output voltage sensor, where operation of each of the plurality of resonant converters is controlled in response to the common control reference voltage or current signal, wherein the common control reference voltage or current signal is communicated to the plurality of resonant converters via a communication link, and the communication link is a single-channel, unidirectional, low-bandwidth communication link with a cut-off frequency of 20 KHz.
