Abstract :
There are various PWM methods proposed for three-phase voltage source inverters. Each method has unique performance characteristics (voltage linearity, ripple voltage/current, common mode voltage/current, switching loss, etc.). Scalar and vector implementation are two main techniques for implementation of PWM methods. Scalar techniques provide equivalent performance to vector implementation and are more favorable for implementation due to simplicity. This paper proposes simple scalar implementation techniques for the popular high performance PWM methods. In the paper the practical implementation of various PWM methods is discussed and the laboratory experiments are shown.
