Development of induction heated hot water producer using soft switching PWM high frequency inverter

This paper presents a new conceptual electromagnetic induction eddy current-based stainless steel spiral type heater for heat exchanger in hot water producer and boiler, which is suitable and acceptable for new generation consumer power application. In addition, an edge-resonant PWM high frequency inverter using IGBTs can operate under a principle of zero voltage soft commutation is developed and demonstrated for a high efficient induction heated hot water producer and boiler in the consumer power applications. This consumer power appliance using soft switching PWM high frequency inverter is discussed and evaluated on the basis of simulation and experimental results.
