In this paper, a new voltage space vector control two-phase inverter - induction motor variable speed system , the system can be widely used in low-power , wide speed run of occasions . Study to complete the design of the two-phase inverter , and composition of the test with a two-phase inverter - induction motor system . The system is a speed open-loop frequency control system by the single-chip machine control circuit , power driver circuit , inverter main circuit , protection circuit . Papers transform the basic equation of the motor the Kron transform and symmetrical components , respectively, to establish a complete system of mathematical models , the preparation of a program of dynamic and steady-state simulation , and simulation analysis of the dynamic and steady-state performance of the system . Relative to the square wave and other power supply control , using the application of of voltage space vector technology in the low-power two-phase asynchronous motor control VVVF torque ripple can be reduced to improve efficiency , with a certain degree of economic and practical .
