A DC-DC converter has a main forward converter stage with a snubber at a source side and a sample and hold circuit at a load side. Feedback is provided by a pulse width modulated controller connected at the load side, which feeds an isolation transformer via a differentiating capacitor. The isolation transformer has its output connected to a pulse regenerator which feeds a driver and a volt-time limiter that connects to a main switch at the source side of the forward converter.
