Aircraft induction heating oven excitation device for heating dish, has MOSFET with on-state resistance and self capacitance values less than or equal to specific values for its terminal voltages greater than or equal to two hundred volts

摘要

The device has converters, placed after sector rectifiers, with a MOSFET (53), and a power factor correction controllers to control the converters. Rectifiers placed after the converters generate an intermediate circuit voltage, and an inverter is connected to the intermediate circuit voltage. The MOSFET has an on-state resistance of less than or equal to 0.1 Ohms and a self capacitance of less than or equal to 200 Pico farad for its terminal voltages greater than or equal to 200 volts.
