Abrégé

A resonant DC to DC converter circuit receiving an input voltage and capable of delivering multiple output voltages, while maintaining excellent cross-regulation with only one power transformer. The circuit of the invention uses trailing edge modulation, along with a new amplitude modulation arrangement which allows for the use of resonance with synchronous rectification and only a single power transformer. Thus, the circuit provides for DC to DC conversion, as well as an amplitude modulation arrangement.
