dear friends
kindly help me out to solve the problem which i am facing in my ckt i was using two p channel mosfet to reverse the polarity of load.there was a problem in the ckt which i will go to explain we have design the ckt to used for reverse load polarity but our ckt is using upto 30v hence we are facing the problem in the mosfet because the vgs(th) is between the 2-5v due which its was firing the mosfet can any one sugget the alternative ckt to due the same for any input voltage and appling pwm across the gate terminal thanking you
when we apply the 30v across the source terminal of the mosfet then they mosfet are switching on with any controlling signal across the gate kindly sugget the alternative circuit
