Abstract :
Proposed the advanced SVPWM algorithm for realization with the air conditioning compressor frequency conversion controlling. By changing the power frequency make motor speed change and achieve to control capacity of air conditioner compressor. And has carried on the theoretical analysis and the research to this algorithm. Based on the basic idea of space vector modulation, by integration of software and hardware, realizing method of PWM waves generated by DSP PWM module in interrupt, and gave the test result. It testified that using DSP to achieve SVPWM have some excellences, such as simple control arithmetic, high speed and convenient realization.
