Abstract

This paper presents the control of SPMSM drive by using diode clamped three and five level inverters. The pulses are generated using Carrier Based Space Vector Pulse Width Modulation (CBSVPWM). Control technique like Field oriented control used for closed loop operation. Compared to conventional Space Vector Pulse Width Modulation (SVPWM), CBSVPWM is very fast and easy to implement digitally, which also reduces the complexity involved in calculation of angle and
sector as in case of conventional SVPWM. It can also be extended to n-level.
