| Abstract |
In this paper, a l8kW brushless wheel motor is described with its original two
stages, soft commutation, power drive. High efficiency is achieved with the motor and the drive. A two stages DC/ AC/ AC converter for variable ac drives using soft commutation technique is described. It consists of a dual-thyristor voltage inverter connected to cycloconverters. It is realized with IGBTs and it supplies trapezoidal currents to the brushless permanent magnet motor. The realized intermediate alternative voltage link, allows to decouple the commutations of the two stages and to obtain non resonant soft switching
conditions. It combines the advantages of a soft commutated converter and those of PWM control (constant commutation frequency, simple control). The experimental results obtained on a bench show that the selected solutions are interesting for multi-motors electrical buses. |
