半正弦波调制技术：一种生成变频正弦电流的新方法

In this paper, a new method for generating variable-frequency sinusoidal current is proposed. This method is based on the series resonant inverter and can be used in adjustable frequency drives. In the proposed method, each half-cycle of the fundamental frequency consists of a number of half-sine waves with different amplitudes and widths, which are arranged side-by-side. In this method, switching...
