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.
