基于非对称脉宽调制下基波功率的电磁炉简易功率控制方法

To simplify power calculation, this article proposes a simple power control method based on fundamental frequency power (FFP) for induction heating cookers in both dc or ac input systems. FFP is calculated from the estimated equivalent resistance and the peak value of the fundamental frequency resonant current, which is obtained through peripheral circuits to reduce the computational load on the d...
