| ABSTRACT= |
{This paper presents a detailed analysis of the switching loss characteristics of various existing discontinuous PWM (DPWM) algorithms, which use only one zero state and advanced DPWM (ADPWM) algorithms which use only one zero state with active state division. These DPWM algorithms reduce the switching losses at any operating conditions when compared with conventional space vector PWM (CSVPWM). Moreover, to reduce the complexity involved in the conventional space vector approach, the proposed PWM algorithms are developed by using the concept of imaginary switching times. By analyzing the switching loss characteristics, the minimum switching loss PWM algorithms are developed for induction motor drives. The theoretical evaluation is validated through the numerical simulation studies}, |
