Abstract :
A power electronic inverter is developed for a high-frequency induction heating application. The application requires up to 160 kW of power at a frequency of 100 kHz. This power-frequency product represents a significant challenge for today´s power semiconductor technology. Voltage source and current source inverters both using ZCS or ZVS are analyzed and compared. To attain the level of performance required, an LCL load-resonant topology is selected to enable ZVS close to the zero current crossing of the load. This mode of soft-switching is suitable to greatly reduce the IGBT losses. Inverter control is achieved via a phase locked loop (PLL). This paper presents the circuit design, modeling and control considerations
