What is it about?
chaotic carrier frequency modulation technique (CCFMT) was applied in TSMC for the first time to spread sideband range and suppress harmonic peak value. Although this technique could suppress EMI, it would increase the probability of narrow pulses. In order to improve reliability, the rectifier in the two-stage matrix converter uses PWM modulation with zero vector to extend the zero current commutation time, solves the narrow pulse problem and simplifies the commutation process.

Perspectives
This paper first proposed the application of CCFMT to TSMC. The proposed new CCFMT can effectively improve the reliability of commutation, solve the narrow pulse problem, and simplify the commutation process.
