Hi againplease give some info on using SCR on DC bus (550VDC ) for softstart and how we can keep on the scr when the load current is zero.
Hi againwhy we use IGBT instead of SCR for softstart?
Hiplease give a block diagram or pdf on it.
Hi againAfter reaching 100% charge ,is there a need to PWM or make IGBT on continuously?
WellI know IGBT and I used them in H bridge, I need to start a test on IGBT as softstart.
Hi again ,But I do not understand what is "take average from that function" please if possible explain more.
Why you need to take average ? because high frequency components of PWm signal , can suffer the load ( especially motors ) . hence a usual term is , using an eliminator filter or as a matter of fact , integrating filter or as a matter of fact three stage LPF for three phase .I know the math routine to integrate and get average of a squarewave,but my question is why I need to average ?
