Pulse Frequency Controlled Resonant Inverter for Different Material Induction Cooking Loads

Abstract

Existent induction cooking application requires high frequency and high efficiency multiple load resonant inverter configuration with independent control that suits for multiple vessels. In this paper, a multiple frequency resonant inverter is proposed for induction cooking application suitable for different material vessels. The proposed inverter is using half bridge configuration and is supplying the loads with power as that of full bridge circuit using a buck boost converter. Pulse Frequency control (PFC) technique is used for output power control. This configuration offers advantages like reduced component count and also improved efficiency. It also provides independent control. This new configuration is simulated with two different vessels and the simulation results prove the benefits of this converter.
