    Ir2100 and the H bridge FETS problem - need help

    ir2100 Hi Gents, I am an electronics tech (not a designer) and have inherited a product that seems to suffer from problems. the circuit has a TL494 that drivers 2 IR 2110s into a H bridge. I have cleaned up lots of the switching noise -using gate resisitors has done lots but I still seem...

    PWM design - want to vary the output voltage down

    pwm help! Hi, Just wondering if anyone can help me - I have a PWM design which switch 24 volts via a TL494 and two IR 2100s into a push pull FET bridge and a large step up transformer which gives an output of 600 volts - which is then recified and smoothed into a small bank of caps and then...
