Gate drive stage
柵極驅動級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電源系統,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、電壓幅值、輸出脈寬,產生雙極性spwm波形,經驅動放大後用于ipm ( intelligentpowermodule )中的絕緣柵雙極型晶體管柵級驅動,以控制電源的輸出電壓和頻率,實現變頻電源的智能數字控制。
