چکیده
This paper presents performance evaluation of an asymmetrical parameter type two-phase induction machine drive using two-phase three-leg voltage source converter (VSC) operating in motoring and generating modes. A system is simulated using MATLAB/SIMULINK. The proposed converter system includes a machine side converter using a three-leg VSC and a front end converter using a single-phase full bridge switched mode converter. The overall converter system is able to operate in a bidirectional power flow mode. For the front end converter, hysteresis band current control is utilized to maintain the DC link voltage constant. The machine side converter provides both unbalanced and balanced twophase output voltages for the machine based on a sinusoidal pulse-width modulation (SPWM) technique. The comparative performance evaluation of the whole system between balanced and unbalanced two-phase motor voltages is given.
