I really love electrical projects but can you please explain to me why mosfet just damaged when the protection diodes is connected to drain and source and the tl494 Ic I followed the directions on the diagram for half bridge inverter but the two mosfet or turning on the same time I even thought I wire the Ic up properly because the two signal or generator good I can see the dead time between the two signal one one channel scope I have but as I did I connected pin 11 12 8together pin 13 14 15 2 together 1 16 together 2.2k resistor to pin 4 7 together 1.uf capacitor 50volt to pin 5 7 and I got good 7v signal on the two 10 9 but when I connected the mosfet gate with 100 ohms resistor and 220ohms to source and gate fast switching diodes to grain and sourced with a 20v battery the mosfet is 55 v and the two mosfet get fire hot and blow I use induction and the mosfet just get hot I use 10 different Ic the same results and my friend in Asian use the same diagram and his circuit work I copy his and the same thing happens 9 Ic just get hot a stop work even before I try the circuit am not understanding why the Ic is not generated two signal in puch pull mode
