| Abstract: | The principle of SPWM modulation in single-phase full bridge voltage mode inverter was represented.The advantage of single polar freqnency-doubling modulation and the reason of adoption were analyzed.The method for relizing SPWM with single polar freqnency-doubling was describled,based on AVR 8-bit SCM AT90PWM2.The prototype of inverter was made,which was applied in gasoline generation set with 1 kW.The inverter has stable function.Finally the experimental results were illustrated.The results show this method can achieve good output waveform,the output voltage waveform is smooth,symmetrical good,and scale distortion is low. |
