Adopting optical fibers for control signal transmission, the driver can solve all the problems regarding drive, protection and voltage insulation for MOSFET and IGBT. The actual application shows that the circuit is simple and reliable with excellent drive and protection performances. Especially the design of combined port is very applicable to series connected IGBT. The series connected IGBT used as the discharging switch of the rigid modulator overcomes low insulated voltage of single IGBT. The design of the grid-driven circuit and the voltage balancing circuit for IGBT are also introduced, giving the output wave of the modulator.
