| Abstract |
In this paper, we propose a new high frequency PWM inverter that converts AC power of 110[V] system or 220[V] system into DC to convert it into high frequency AC by using a new high frequency inverter power system. The proposed voltage-type full-bridge ZVS-PWM high-frequency inverter has shown that power control can be applied to the phase change. The phase shift control method is characterized in that the current penetration depth of the induction heating sub-system can be always kept constant because the power can be controlled at a constant frequency, and the conductivity and EMI noise level are not dispersed. From the above results, it is confirmed that it is effective to improve the efficiency of the proposed high frequency PWM inverter system. |
