This paper presents a regenerative cascade inverter topology with direct active power control scheme. From the mathematical model of the proposed regenerative cascade inverter, the instantaneous active power and reactive power are derived. Based on the instantaneous abc theory, direct active power feed-forward control is proposed to reduce AC power and voltage fluctuation in DC link. Moreover, ...

The objective of this paper is to present a multilevel inverter topology for induction motor with open-end winding. Multi level inversion is achieved by feeding an open-end winding induction motor with a two-level inverter in cascade with three auxiliary circuits from one end and a single two-level inverter from the other end of the motor. The combined inverter and auxiliary system with open-en...

In high power high voltage application BLDC motor are widely used because of high efficiency, simple construction, low cost less maintenance and high torque or high output power per unit volume. For driving the BLDC motor we required inverter. PWM inverter which gives good performance. In two level inverter there is a problem of harmonics distortion, lower electromagnetic interference, high DC ...
