AbstractDomestic Induction Heating (IH) technology has become more popular in recent years due to features such as cleanness, safety, quicker warming, and higher efficiency, which outperforms other traditional heating systems. Most of the ac–ac converters used in home appliances is based on single output dc link inverters, which provide a cost effective and direct solution. However, a two stage power conversion drops power density and efficiency. Nevertheless, the complex control scheme and higher cost has prevented it from being used in cost oriented applications, such as home applications. This paper suggests the operation of Single-Phase Matrix Converter (SPMC) that could synthesize a greater AC output voltage from a given AC supply voltage.  Insulated Gate Bipolar Transistors (IGBTs) are used to implement the SPMC topology while the well-known Sinusoidal Pulse Width Modulation (SPWM) scheme is used as the switching technique to synthesize the output waveform. The proposed topology reduces significantly the number of power electronic devices and complexity, leading to an efficient, flexible, and cost effective solution. The Matrix Converter [MC] block is shared with a high number of induction loads, the overall cost is significantly reduced and the proposed topology can target the home appliance market. In order to verify the proposed Matrix Converter [MC] topology, modeling and simulation was carried out by using MATLAB.
