A novel AC-AC converter based SiC for domestic induction cooking applications

Abstract

this paper presents the analysis and design of a new high frequency ac-ac converter applied to domestic induction heating. The proposed topology uses only four switches to control power. Converter operation is same as a conventional class D inverter. Working above the resonant frequency, a sinusoidal input current and a unit power factor are obtained. To bring higher efficiency and power density, application of emerging SiC technology in proposed converter has been evaluated. The analytical and simulation results have been verified by means of a 380-W induction heating prototype.

A Bridgeless BHB ZVS-PWM AC–AC Converter for High-Frequency Induction Heating Applications

“…A non-boost type single-stage ac-ac converter has been proposed [11], however the DBR is necessary and the costeffectiveness is still in a challenge. Another types of singlestage ac-ac converter have been proposed by using bidirectional switches [12] [13], but the reliability of this new type of power device is not up to the practical level. The capacitorboosted ac-ac converter that is free of the DBR, named as "bridgeless", has been proposed [14] [15], however no actively voltage regulation can be performed.…”

Single‐Stage ZVS‐PWM AC‐AC Power Converter Using All SiC Power Module for High‐Frequency Induction Heating Applications

“…There are several reports on evaluation of HF IH converters using SiC power devices, particularly, HF inverters [7][8][9][10][11]; however, we are not aware of any study cases or academic papers verifying soft-switching techniques, especially ZVS, using all-SiC power modules with regard to SiC-MOSFET characteristics. In this context, it is important to experimentally verify all-SiC power modules, combining high withstand voltage, low on-resistance, and zero tail current, as an alternative to Si-IGBT power devices (modules or discrete components), being currently the mainstream in home and professional high-frequency (HF) IH applications.…”

An Effective Switching Algorithm for Single Phase Matrix Converter in Induction Heating Applications

“…All these converters use HB-SRI, which relies on four-quadrant equivalent switching devices that are combination of two anti-series IGBTs. In [30], a SiC based AC to AC converter for domestic IH has been proposed, which uses solely four switches and only single stage energy conversion has been achieved. Moreover, single-phase matrix converter (SPMC) (which is the part of Matrix Converter) may also be used for IH applications [31].…”
