Abstract :
This paper presents a simple speed control method of an asymmetrical parameter type two-phase induction motor drive using a three-leg voltage source inverter (VSI). The two-phase induction motor is adapted from an existing single-phase induction motor resulting in impedance unbalance between main and auxiliary windings. Thus in order to improve the performance it needs an unbalanced phase supply. Mathematical model is derived for the simulation. The design of a speed controller is fully given. The overall system is implemented on a DSP board. The validity of the proposed system is verified by simulation and experimental results.
