Abstract
Pulse width modulation is the use of the microprocessor to the digital output of analog circuits for the control of a very effective technology, widely used in measurement, communications, power control and many other fields with the transformation, which generates three-phase waveform of the overall effect of the premise in order to approximate the ideal of the electrical air-gap circular trajectory for the purpose of rotating magnetic field with different inverter switching model to the actual magnetic flux close to the base circle, the results from their decision to switch the inverter to form a PWM waveform. In this paper, analysis of SPWM, SVPWM control principle to MATLAB/SIMULINK as a platform to build on the coordinates of two-phase induction motor simulation model, and under way in the SVPWM AC Drive system simulation.In modern society, the measurement of electrical power is becoming more and more important. The traditional way of power measurement is manual, its accuracy is not good and sometimes troublesome. Along with life quality enhancement, the measurement is gradually going to wireless and remote control. Lets the measurement become more accurate, more reasonable, is the development direction.
