This paper seeks to investigate the performance of a DTC strategy dedicated to the control of four‐switch three‐phase (B4) inverter fed induction motor drives. The major advantage of the B4 inverter is the reduced number of the involved power switches which opens up crucial cost benefits.
The principle of operation of the B4 inverter fed induction motor drive is recalled in a first step. Then, the basis of the proposed DTC strategy is presented. Following this, the synthesis of the corresponding vector selection table is carried out considering a subdivision of the space vector plan into sixteen sectors.
It has been found experimentally that the B4 inverter fed induction motor drive offers, under the proposed control strategy, interesting performance.
This work should be extended considering a comparison between the performance of B4 inverter fed induction motor drive under the proposed DTC strategy and those of the B6 inverter fed induction motor drive under the popular Takahashi DTC strategy.
The paper proposes a new DTC strategy dedicated to induction motor drives fed by B4 inverter. This reduced structure inverter is of great interest for large‐scale production industries such as the automotive one as far as cost‐effectiveness is concerned.
