Abstract
This paper presents a new electromagnetic induction eddy current-based spiral type dual packs heater using a high frequency resonant inverter or the induction heating type heat exchanger, which is more suitable and acceptable for the consumer power applications. In addition, the proposed active voltage clamp edge-resonant soft switching PWM high frequency inverter using IGBTs can operate under a principle of the zero voltage soft commutation scheme. This inverter is developed for a high efficiency induction heating (IH) hot water producer or IH boiler and super heated steamer packed partially inside a variety of pipeline plants. This innovative consumer power appliance using soft switching PWM high frequency inverter, designed for the IH fluid heater, is evaluated and discussed on the basis of simulation and experimental results.
