    Abstract: KI9-86-015 MOSFET FULLBRIDGE SWITCHING REGULATOR HAVING TRANSFORMER COUPLED MOSFET DRIVE CIRCUIT An FET full bridge regulator has a driving transformer for the gates of the power FETs of the regulator, and a driving circuit for the primary of the driving transformer, the driving circuit including a full bridge formed by first and second sets of driving FETS, each set formed by a complementary pair of FETS and being connected across the transformer primary, one FET of each set being driven ON to together form a series of conducting paths across the primary of the transformer in the absence of driving signals. The voltage supply for the driving FETs in the driving circuits of the primary of the driving transformer includes a resistance across which there is developed a voltage proportional to the current drawn by the driving transformer primary in each half cycle of its operation for reducing imbalance between the half cycles.
