© 2019 IEEE.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.
