configurations, a CSI and a VSI. The CSI is fed through a dclink inductor and a threephase controlled rectifier, while the VSI has a dc capacitor as its energystorage elemen t. The large CSI is used as the main inverter to feed and control inductive loads such as induction motors. In fact, the small VSI, connected in parallel with the CSI,
The braking of an induction motor is explained below in details. 1. Regenerative Braking. The input power of the induction motor drive is given by the formula shown below. Where φ s is the phase angle between stator phase voltage and the stator phase current I s. For motoring operation, the phase angle is always less than the 90º.

Description. The SixStep VSI Induction Motor Drive block represents a classical openloop Volts/Hertz control, sixstep or quasisquare wave drive for induction motors. The block obtains the stator supply frequency from the speed reference (neglecting the slip frequency). This frequency is used to compute the stator flux position necessary to generate the sixstep pulses for the threephase ...
This paper presents a carrierbased unbalanced pulsewidthmodulated method for a twophase fourleg voltage source inverter (VSI) and its realization for an unsymmetrical twophase induction motor. A modulation strategy is developed to synthesize unbalanced twophase output voltage waveforms based on the unipolar modulation technique with openloop V/f control.
