Research Of The Control Voltage Economic Device For The Asymmetric Load

Motor is the electric device which use most widely and consume the most energy,so it is important to research its economic operation. So decreasing loss of motor should be researched. This article focus on the motor which supplied by 1140v and driving the asymmetric load, prepares to manufacture the control voltage economic device basing on PWM, achieves to control the voltage on the motor in order to decrease the loss of motor and save the electric energy. The research is valuable in application and study of science. This article research the regulation of the asymmetric load and put forward the economic theory and the control method of the control voltage economic device for the asymmetric load in special voltage level 1140v,design the main circle of the control voltage economic device for the asymmetric load and select the component,at last,simulate the main circle of the control voltage economic device for the asymmetric load by the electronic simulation software PSPICE,the conclusion indicates that the design can meet our desirability．Luo xiong (Power System Automation)...
