Hybrid controlled dual frequency inverter for two load induction cooking application

摘要

Induction heating applications have become more popular due to its advantages like non contact heating, environment friendly and high efficiency. In this paper, a two load induction heating system is proposed for cooking applications. A single full-bridge inverter is powering the loads at two different frequencies. These loads are controlled independently and simultaneously. The prototype has been built and tested for 115 W of low frequency and 60 W of high frequency power. Phase shift control and pulse density techniques are used for power control. Experimental results presented are in good agreement with simulation results.
