Abstract
An inverter circuit using transistors in the switch mode, suitable for induction heating for cooking and sonar applications. Diodes are used in the base circuit of the transistors to postpone conduction and prevent shoot-through, and diodes are used to limit diode recovery time closely to recovery time of transistor base while protecting against base-emitter avalanching.
