Abstract

In this work, a new voltage space vector PWM method is developed. The problem of exact generation of small voltage vectors is discussed. Two methods for generating small inverter output voltage vectors are proposed. The influence of dead time is explained and its effect on the motor current is compensated. A squirrel cage induction motor with reduced supply voltage is used for testing the developed algorithm. Simulation and experimental results are carried out using fixed-point (DSP) and (FPGA). In addition, the practical realization of the proposed algorithm is discussed.
