PV Power Based Duty Cycle Control of Quasi- Resonant Inverter for Induction Cooking Adem Sular Van Yuzuncu Yil University, Faculty of Engineering, Electrical-Electronics Engineering Department Van, Turkey adem_sular@hotmail.com Naci Genc Van Yuzuncu Yil University, Faculty of Engineering, Electrical-Electronics Engineering Department Van, Turkey nacigenc@yyu.edu.tr Ali Mamizadeh Van Yuzuncu Yil University, Faculty of Engineering, Electrical-Electronics Engineering Department Van, Turkey alimamizadeh@yyu.edu.tr Muhammet Karaca Van Yuzuncu Yil University, Faculty of Engineering, Electrical-Electronics Engineering Department Van, Turkey mkaraca1256@gmail.com Abstract—In this study, photovoltaic (PV) power-based duty- cycle control is recommended for induction cooking (IC) topologies. The output power of the PV panels changes due to the change in solar irradiation. Based on this PV output power, variable duty-cycle control is recommended for single-switch quasi resonant inverter which is often used for IC applications. In the study, the output power is controlled by using the PV power value produced by MPPT to control the duty-cycle rate of the switch of the resonant inverter according to the variable input power, depending on the variable solar intensity and keeping the temperature and frequency constant. Thus, a quasi-resonant inverter is proposed which adjusts its own power increase or decrease according to the power change in the PV panel. This results in the batteries to be used in the system are allowed to have a longer life and constitute a significant financial gain. PV- powered single-switch quasi resonant inverter circuit with a rated power of 2kW was modeled in Matlab/Simulink environment and the results were presented. Keywords— Photovoltaic, Duty Cycle Control, MPPT, Induction Cooking, Quasi-Resonant Inverter. I. INTRODUCTION Compared to the past, induction cookers have increasingly gained a significant market share in the domestic cooker sector. The advantages of induction cookers such as energy saving, ease of cleaning, high efficiency and fast heating caused these improvements. These advantages are due to eddy currents that cause induction heating and heating at the bottom of the pot caused by hysteresis losses [1]. However, in addition to these advantages, induction cookers have disadvantages such as the suitability of pots and pans and the high initial cost of installation [2]. In addition, the increase in electrical appliances together with the developing industry increases the demand for energy day by day and causes unconscious consumption of energy resources [3]. This situation causes environmental disadvantages such as global warming, seasonal changes and pollution. Therefore, in recent years, innovations and developments related to the use of renewable energy sources have emerged. Since the solar energy is inexhaustible, clean, environmentally friendly and is an energy source that forms the basis of other renewable energy sources, it has an important usage area within the existing renewable energy sources [4-5]. The technology that enables us to benefit from solar energy is known as PV panel. The operating principle of PV panels is the integration of multiple PV modules connected in series or parallel to provide the necessary power, which converts solar energy from the sun into DC electrical energy. Increasing use of solar energy will create new areas of use. One of these applications is the PV based operation of induction cookers. PV based induction cookers can be used in kitchens of panel vans as given in Fig. 1. In PV-based induction cookers, the problem of limited current draw in the city network can be eliminated [6].
