Abstract


In this paper, the three-phase voltage -type high power factor PWM converter circuit theoretical analysis and simulation , experimental research . Elaborate on the mathematical model of the three - level voltage -type PWM converter working principle and its control method . On this basis , the validity of the SVPWM control strategy , based on space vector and the instantaneous reactive power theory , CORDIC algorithm, applied to the three-phase voltage -type PWM control of high power factor rectifier , through MATLAB simulation proved this method . Secondly, the analysis of the three - phase voltage-type inverter principle, model , a control method and to study the PWM trigger pulse control signal generating technology lap hardware and the DSP, CPLD chip test circuit , resulting in a trigger pulse signal , the test results prove the rationality of the design .
