| Abstract: | A new control method for high frequency sine wave inverter is presented in this paper.A SPWM output voltage is obtained through adopting phase-shifted full bridge,using integrate chip ML4818 and demodulating the secondary cycloconverter.The structure of the sine wave inverter is given,the working principles of the control circuit and voltage feedforward are analyzed. The experimental result shown that the proposed inverter owns the advantage of simple control scheme,universal range of input voltage and high efficiency. |
