In many applications further cost reduction for the drive is one of the important aspect, and thus, a reduction of the number of power switches in the inverter should be a main consideration. These topologies (B4) are employing four switches and four diodes as a practical alternative to the conventional (B6) inverter with six switches and six diodes. This paper presents an analytical model and analysis of the time response of the motor currents for a four-switch inverter driving a three-phase induction machine. As the phase voltages are in principle asymmetrical, first the asymmetrical space vectors are expressed in the symmetrical forms. Next, the mathematical model uses mixed descriptions in the p and z domains. (The Laplace and modified z-transform). Finally, analytical results are verified experimentally on a 0.75 kW B4 inverter.
