  1. The feedback of the output voltage is the major control loop. to achieve better frequency response and disturbance rejection of the input voltage, a input voltage feed - forward system is introduced in control loop. the duty - cycle of pwm applied at the gate of power mosfet is modulated by both input and output voltage

    該晶元採用的方式為型pwm (脈沖寬度調, pulsewidthmodulation )方式,以輸出反饋作為主要參量,同時為了提高晶元對輸入擾動的響應速度,採用了輸入前饋方法,將輸入因素引入了反饋環中,通過對輸入輸出的檢測,加在功率mos管上矩形脈沖的占空比,進而調節輸出
  2. According to the following design theory : the dsp calculates in real time and produces three phases spwm waves to control the on or off of the 6 igbts in ipm respectively. ipm then inverts the commutated single phase direct current ( insulated gate bipolar transistor ) into three phases alternating current. when modulated signals of spwm are changed, the on - off time of switches also changes, so as to the voltage and frequency of output signals

    本文提出了一種基於dsp (數字信號處理器tms320f240 )的通用的三相間接變頻源系統,利用分段同步調製法和混合查表法,實時計算不同頻率下的采樣周期、幅值、輸出脈寬,產生雙性spwm波形,經驅動放大後用于ipm ( intelligentpowermodule )中的絕緣型晶體管級驅動,以源的輸出和頻率,實現變頻源的智能數字
