High power, high frequency resonant inverter using MOS controlled thyristors

摘要

A high power, high frequency inverter has series/parallel resonant inverter elements and employs MOS controlled thyristors (MCTs) in the switching circuit. The resonant inverter elements include a split inductor for reducing peak voltage across the switches. A fault protection circuit cause the power interruption for a short interval before restarting the circuit. High current density is achieved by means of multilayer ceramic chip capacitors and gap ferrite planar inductors.
