ABSTRACT:
A self oscillating power converter uses two MOSFET transistors connected across first and second primary windings. Each MOSFET is controlled using a gate control circuit located in a feedback path. Each gate control circuit is driven by a gate drive winding which is transformer coupled to a primary winding and which is phased with the primary winding such that regenerative feedback causes accelerated sequential turn-on and turn-off of the associated MOSFET transistor. Each feedback path includes a capacitor for charging in response to the voltage generated across the gate drive winding to initiate turn-on of the MOSFET transistor and a resistor for discharging the capacitor to initiate turn-off of the MOSFET transistor. The power converter can be configured as a push-pull converter in either a common-drain or common-source configuration. The power converter can also be configured such that at least one MOSFET transistor is capacitively coupled to a primary winding. Further, the power converter can be configured as either a full-bridge or a half-bridge converter.
