Six pulse bivariate AC-AC frequency control system for the study, research and analysis with simulation tools combined with actual experimental results of the the trigger control strategy of the speed control system in different applications . First , through the analysis of a large number of the inverter output waveform is given based on the theory of the general laws of the control strategy optimization ; Then, simulation experiments in Matlab / simulink simulation model , and the test results are analyzed ; Finally, when creating the experimental platform debugging optimized inverter output waveform , based on the effect of motor control trigger control strategy to optimize summarized . Different modulation wave ( triangle wave , sine wave , square wave , step wave , trapezoidal wave ) the downconverter output voltage , the comparative analysis of the current waveform from the inverter output sinusoidal waveform , symmetry , harmonic content considering all aspects of the speed control system with a carrying capacity and speed control mode , the to combine simulation experiments of the the six pulse wave cYCLOCONVERTER trigger control strategy were summarized . The experimental results show that : reasonable trigger control strategy can make the system better governor , the motor run more smoothly , efficient and fast .
