Multiple-output boost resonant inverter for high efficiency and cost-effective induction heating applications

Abstract

Induction heating is an efficient and high performance heating method which already has a significant market penetration and economic impact due to its benefits inherent to contactless energy transfer systems such as quickness, cleanness, and safety. In order to improve the efficiency and performance of modern induction heating systems, this paper presents a multiple-output boost resonant inverter. The proposed topologies significantly improves the converter efficiency due to the reduced current level while being able to supply several induction loads. Consequently, a high-performance and cost-effective implementation is achieved. The proposed converter has been tested through a 3.6-kW dual-output prototype, proving the feasibility of this proposal.
