the speed control of three phase induction motor using six step( conduction). The SPWM based VSI fed induction motor drive is modeled using the Simulink block. SPWM is the most efficient and more reliable technique to controlled the output voltage of VSI. This technique also minimizes the lower order harmonics and improves the VSI response.

A dead-time compensation method in vector-controlled pulse width modulator (PWM) voltage source inverters (VSIs) is proposed. The method is based on a feedforward approach that produces compensating signals obtained from the I/sub d/-I/sub q/ current and inverter output angular frequency references in the rotating reference (d-q) frame. It …

Hence, a three-level CHB VSI fed PMSM drive is used in this paper. The objective of this paper is to address the two major problems associated with the conventional HM for a three-level VSI fed PMSM drive, namely, (i) large variation in switching frequency and (ii) lack of control over the maximum switching frequency.

The proposed schemes are further implemented on an industrial embedded control system. Their performance tests are conducted on a PMSM under static and dynamic conditions and compared with the extended Kalman filter without VSI nonlinearity compensation. The effectiveness of the proposed approaches is proved by the experimental results.
