Abstract:
Recently,the sine pulse width modulation(SPWM) control technology has been widely used in power electronic system. However,the output voltage of the inverter contains some harmonic which will have a great influence on the load. In order to make the load work normally,we must consider how to eliminate harmonics. Considering the influences of power source resistance and load resistance,this paper discusses the insertion loss of LC filter and analyzes the related parameters of LC filter in detail. At the same time,a filter is designed under the circumstance of normalization. Finally,the LC filter is simulated with MATLAB to verify its effectiveness.
