Following the climatic changes, there is a universal commitment to reduce greenhouse gas emissions, especially those due to mobility. A particular interest is addressed to hybrid propulsion systems, which are currently considered as viable candidates for a sustainable mobility. Within this commitment, the study proposes an approach to improve the cost‐effectiveness, compactness and reliability of the electric drive unit of hybrid propulsion systems. This is achieved thanks to different associations of brushless DC motors (BDCMs) and reduced topologies of DC/AC converters such as the four switch inverter and three switch inverter. A special attention is focused upon the analysis of the sequences and commutations characterising the six‐phase and three‐phase BDCM drive operation. Implementation schemes of dedicated control strategies are given. Moreover, a comparison of selected features related to the ratings of the investigated BDCM drives is carried out and commented. Experimental results are provided to validate the performances of a reduced structure inverter fed three‐phase BDCM under the dedicated control strategy.
