Abstract: Analysed the principle of single-phase induction motor with asymmetrical windings,and derived an algorithm for controlling single-phase motor combining SVPWM，then built a simulation model for controlling system in Matlab7.0,and gave the simulation result.The result shows that  can get good performance using this algorithm to control single-phase with asymmetrical windings.
