Research on TSMC Based on Optimization Commutation Strategy

This paper analyzes the double space vector modulation strategy of the two-stage matrix converter(TSMC) and it's zero current commutation principle,a new zero vector optimization commutation strategy is proposed to make TSMC commutation more secure and reliable while ensure its excellent input-output performance.An experimental prototype is established based on the controller of digital signal processor(DSP) and complex programmable logic device (CPLD).The experimental results verify the modulation strategy and commutation principle of TSMC,it also indicates that TSMC has excellent input-output performance.
