Abstract
The purpose of the paper is to present a new inverter control technique whi ch not only mitigates the common mode voltage for motor drives but also sig nificantly reduces the calculations required for high switching frequency c ontrol, in comparison with the conventional space vector modulation techniq ue. Moreover, it is demonstrated that the presented technique improves the quality of inverter control by randomising the inverter switching frequency , thereby spreading the first dominant harmonic cluster which contributes t o the noise. Experimental results derived from a microprocessor-based exper imental drive system are presented to confirm the theoretical analysis.
