circuitry, especially since the gate drivers typically use a
supply voltage between 5V to 12V. The preregulator circuit
finds wide use in fully synchronous forward converters,
push-pull converters and full-bridge converters.
Generate a bias supply for a forward converter using similar
techniques to that of the flyback converter. Figure 3a to 3c
detail the three common bias circuits for the synchronous
