Interleaved Resonant Boost Inverter Featuring SiC Module for High Performance Induction Heating
Induction heating has become the technology of choice in many industrial, domestic and medical applications due to its high efficiency and performance. This paper proposes an interleaved resonant boost inverter featuring SiC three-phase module to achieve a high efficiency and performance induction heating power supply. The proposed converter achieves high efficiency by reducing the current through the devices, while the use of an interleaved full-bridge configuration reduces input current ripple and provides additional control degrees. The proposed converter has been designed, implemented, and tested experimentally, proving the feasibility of this proposal.
EXISTING SYSTEM:
In all the discussed approaches, the inverter is the core of the power converter a and is commonly implemented using single-switch topologies for low-medium power applications, and the full- bridge topology for high power applications. Although Si IGBT is the technology of choice, in recent years wide bandgap devices and specially SiC, have enabled significant advances in performance and plays currently an important role in modern IH systems.
PROPOSED SYSTEM:
This paper proposes an interleaved boost resonant inverter topology in order to provide an efficient and high performance IH power supply. The proposed topology achieves high efficiency by reducing the current through the power devices and inductor, while the use of an interleaved configuration enables reduced input current ripple. Besides, the boost full-bridge inverter provides additional control degrees, enabling fine output power control. The proposed converter takes advantage of a three- phase SiC module to achieve a high power density and performance implementation.
CONCLUSIONS
In this paper, an interleaved boost resonant inverter for induction heating applications has been proposed and deeply analyzed. The proposed converter enables high efficiency and high performance operation, with improved control and reduced input current ripple. An analytical model for the proposed converter has been provided, and a detailed power loss analysis has been performed, enabling the converter design and optimization. The proposed converter has been designed and implemented taking advantage of SiC technology, and the main experimental results proving the feasibility of this topology has been discussed. As a conclusion, the interleaved boost resonant converter is proposed as a high performance topology for industrial IH applications.
