Driver system for MOSFET based, high voltage, electronic relays for AC power switching and inductive loads
A method and apparatus provides for high-speed switching of high-voltage and high power MOSFET-based solid state relays. A driver for a MOSFET based, high voltage, high current electronic relay includes a current supply for actuating the switching circuit and a transformer arrangement coupled to the current supply for receiving the supply of current from the current supply. The transformer arrangement is adapted for coupling with the switching circuit for selectively applying a predetermined voltage to the switching circuit which establishes the switching circuit in switch conducting or switch isolation.
