Electromagnetic induction eddy current-based far infrared rays radiant heater using soft switching PWM inverter with duty cycle control scheme

Abstract

This paper presents an innovative prototype of a new electromagnetic induction eddy-current heated type far infrared rays radiant heating appliance using the voltage-fed edge-resonant ZVS-PWM high frequency inverter using IGBTs for food cooking and processing. This soft switching inverter can operate under a constant frequency variable power regulation scheme in order to heat the spiral planar induction heater made of the stainless steel plate. This power electronic appliance with soft switching high frequency inverter using IGBTs has attracted special interest from some advantageous viewpoints of safety, cleanliness, compactness and rapid temperature response, which is more suitable for consumer power electronics applications.
