Home appliances are responsible of a significant part of residential energy consumption and have a major impact in the overall energetic system efficiency. Most of them perform an indirect ac-dc-ac conversion in order to obtain the required output voltage level and frequency, depending on the applications. Thus, a high-efficiency and power density converter is required for this application where cost-effectiveness...
Induction heating has evolved in recent years towards flexible cooking surfaces with multiple control possibilities. This paper reviews the series resonant multi-inverter topology as a versatile and cost-effective solution for multi-load induction heating systems and analyzes pulse density modulated control strategies with a special focus on the EMC behavior. The main control strategies are explained...
Magnetic hyperthermia is a promising cancer treatment technique based on selectively heating cancer cells to cause their death using the induction heating principles. In order to optimize the magnetic field generator, this paper proposes the design of a high-frequency high-power density inverter taking advantage of the recently developed high-voltage GaN devices and using an insulated metal substrate...
The power transistor (IGBT) is one of the most important components of the inverter of domestic induction cookers. For this application the maximum junction temperature (Tjmax) of the IGBT is one of the most critical design parameters because the cooker has to decrease the output power when the junction temperature is near to Tjmax of the device. The junction temperature (Tj) of the IGBT principally...
