In this study, three system approaches for implementing an all metal induction cooker are compared and analyzed. To perform equal and quantitative comparisons and analyses, the resonant network of each system is designed under equal input/output conditions using the same power semiconductor devices. Based on the comparison and analysis results, the appropriate method is applied to a 3.2 kW prototype to confirm the heat transfer efficiency, which can be estimated by measuring boiling time. In addition, improvements of the recommended control methods are discussed.
