| Abstract: | The thesis proved an improved equal area algorithm by analyzed the intrinsic methods based on the SPWM. In the im- proved equal area algorithm, the geometry center of sampling period is regarded as the rectangular pulse center of SPWM wave. Uti- lizing its highly speed operational capability in TMS320F240 DSP chip, we put forward the new hardware mode to eliminate the har- monic wave of inverter in real time. Testing the new hardware method DSP- based in laboratory, the emulation conclusion shows that the control using the new hardware mode can improve the accuracy of the invert output and ideal voltage wave can be output. |
