after testing ir2110, i am moving on to test 3 pairs of igbt with 3 ir2110....
but one situation is making me frighten...first of all see my circuit diagram attached below...
As 3 IGBT pairs are there, and I have to give complementary input to each gate, i.e. if high side igbt is on then low side must be off...
my input source is microcontroller , I have used 3 output pin A,B and C shown in image., and I will use 7404 IC to invert the states of A,B,C to get low side input....
now real problem is that, during the transition from 1 to 0 or 0 to 1...I fear momentary high and low side IGBT would be 1 and both at a instant becomes 1, resulting shorting Vcc and Gnd...because frequency would be several kHz....
I read an application note---an-7511 ...below is the link
https://www.electro-tech-online.com/custompdfs/2009/07/AN-7511.pdf
in page no.5 it is written that there must be 10-15 degree delay between state transition so to avoid igbt destruction and cross conduction.......
how tio achieve this?? I am confused??
I have heard some igbt driver comes having built in delay....
I used IR2110, but dlon't that it provides delay or not???
he;p with this....
