High frequency eddy current-based far infrared rays radiant heater using zero voltage soft switching inverter with asymmetrical PWM implementation

Abstract

This paper presents an innovative electromagnetic induction eddy current heated type far infrared rays radiant heater using the voltage-fed edge-resonant ZVS-PWM high frequency inverter for food cooking and processing. Its operating principle is described. Its operating performances such as the voltage and current peak stress. soft switching condition, and power regulation are illustrated on the based of duty cycle time ratio control strategy due to asymmetrical PWM scheme. The effectiveness of the electromagnetic induction eddy current based for infrared radiant heater using the soft switching inverter is treated here.
