  • Drive transformer isolation adaptive drive circuit
    Patent number: 9270158
    Abstract: A drive transformer isolated-adaptive drive-circuit includes a power supply, a first MOSFET and a second MOSFET, the drain electrode of the first MOSFET coupled with the positive electrode of the power supply, and the source electrode of the first MOSFET coupled with the drain electrode of second MOSFET; the source of the second MOSFET coupled with the negative electrode of the power supply; a drive transformer having a first winding and a second winding; a first fast drive circuit, one end coupled with the first winding, the other end coupled with the first MOSFET; a second fast drive circuit, one end coupled with the second winding, the other end coupled with the second MOSFET; a first adaptive-dead-time control sub-circuit; and a second adaptive-dead-time control sub-circuit.
    Type: Grant
