Webpredict the switching times of the MOSFET and hence allow the estimation of switching losses. Since it is the time from the end of t1 to the end of t3 that causes the turn-on … WebAs a result, 3.13 A rms will flow into each switch, causing the losses and failure rate in each MOSFET to be reduced, giving 5.962 failure/10 6 h for each pair of active switches. Case 3 (passive parallel redundant): S 1 and S’ 1 were in parallel. State 0: Only S 1 was active, and S’ 1 was on standby. Web\$\begingroup\$ It looks like your switching time will be limited by the delay and switching time of the driver chip. There is little difference between on and off, the output stage of the driver chip is a totem pole driver. You can speed up the turn-off time with a diode. 30-40 ns is a very short time :-) If you are concerned about the power dissipation, you need to … pottery plus hesperia ca
