A new phase shifted zero voltage switching (ZVS) self-oscillating pulse width modulation (PWM) high frequency stage-3 inverter with flying capacitor and neutral point clamp diodes for an induction heating application is presented in this paper. To achieve the peak voltage with less- harmonic output at above resonant frequency, this network has been customized and changed in reference with full-bridge network topology. Then, an input dc voltage equal to Vd⁄2 applied to control stress of device voltage. The model is operational between 50 and 80 kHz at the rated 440V dc voltage and can feed maximum power of 1000W to the grid. The heating as well as hardening of the iron has been done at 800°C temperature. The principle of operation of phase shifted AM-ZVS-PWM inverter along with the experimental results are presented in this paper to verify the performance of the system.
