Dual-Output Extended-Power-Range Quasi-Resonant Inverter for Induction Heating Appliances

Abstract

Induction heating technology provides efficient and reliable heating processes that outperforms other classical heating methods based on fossil fuels or resistive heating. Among its many industrial, domestic and biomedical applications, domestic induction heating appliances are a popular choice due to these advantages. This technology requires high-performance and cost-effective inverters that takes the most of the power devices and the converter topology. Depending upon the desired performance and output power range, different power converters are employed. However, currently, most platforms rely on the well-known series resonant half-bridge topology. Single-switch topologies offer a cost-effective implementation but are limited to the low-cost low-performance markets due to their limitations in terms of output power and power control.In this context, this paper proposes a high-performance dual-output quasi-resonant inverter for modern induction heating appliances. Unlike state-of-the-art proposals, this converter achieves full output power operating range up to 3.6 kW. Consequently, it provides a high-performance costeffective alternative to current implementations. The proposed converter is analyzed in this paper and experimentally verified using a dual-output 3.6-kW induction heating appliance prototype.

“…For the IH system research area, researchers have mainly focused on the development of resonant inverter topologies [11], control systems, the induction coil design [9], and the equivalent load estimation of the coil-cookware load [12]. In IH systems, there are three common resonant inverter topologies [11]: single-switch quasi-resonant [13], half-bridge, and full-bridge inverters. The control system performs several functions [8]: including output power control, soft-switching operations to reduce switching losses [14], security and protection, and cookware load recognition [12].…”
