Use Singlechip To Realize Voltage Vector Control Of Tow Phase Asynchronism Motor

This paper study a two-phase inverter-fed induction-motor drive,which can be widely used for low-power , variable speed drive system.The study has completer the design of two-phase inverter and made up of the two-phase inverter-motor system for experimental use .It is a variable frequency adjustable speed system with a open-loop control of rotational speed,which consists of singlechip controller, power drive device, Inverter-Fed device, a Low Power Tow Phase induction motor and safeguard circuit. Accurate mathematical model is set based on the whole system,and simulator program of dynamic and steady condition is established ,which is use to calculate the dynamic and steady performance by Kron and symmetrical coordinate converter. By simulator calculation and experimental research with specific parameter of the system,a comparise is made between predicted and experimental characteristics experimental measurements are shown to compare closely with corresponding theoretical result.It is compared with square wave power supply and other system from system efficiency ,torque pulasation and the effect of two-phase inverter capacitance. These illuminate that Voltage Vector Control of a Low Power Tow Phase Inverter-Fed induction motor Driver as a Pulse Width Modulation control of a two-phase inverter-fed induction motor driver system can effectively cancelled the low harmonic and improve the system performance.
