Cascaded load inverter configuration for induction cooking application

Abstract

In this paper a single full bridge resonant inverter with independent output power control of two cascaded loads for induction cooking application is presented. In proposed configuration, the full bridge inverter can be operated with constant switching frequency and constant duty ratio for efficient zero voltage switching. Independent output power control of each load is done by varying the duty ratio of respective switching device at load. The proposed configuration can be extended to multiple loads. It is more reliable for multiple load induction cooking application. For theoretical predictions, the proposed configuration of cascaded load inverter configuration for induction cooking application with independent control of each load is simulated in ORCAD (P-Spice) environment.
