Abstract: Permanent magnet brushless DC motor (BDCM) has been widely used in industrial applications because of its low inertia, fast response, high power density, high reliability and maintenance-free. Firstly the thesis will introduce the background and brushless DC motor. Then two novel soft switching inverters will be proposed. They are resonant DC link inverter and resonant pole inverter. These inverters possess the advantage of low switching power loss, low inductor power loss, low DC link voltage ripple, small device voltage stress, simple control scheme, eliminating a stiff DC link capacitor bank that is center taped. Then a hybrid controller for the BDCM variable speed drive system which holds the advantages of both PI and fuzzy logic controller is proposed. The design of the controller will be described in detail. Lastly, a steady state reference current technique is offered. Conventional controller combined this technique holds the advantages of fast response, little overshoot, little oscillation, robust and so on.
