2 Transistor Forward Summary
This is a unipolar topology
– Superjunction already works well
– Body diode performance is unimportant
Switch losses are dominated by:
– Conduction
– Turn-on speed
– Eoss
– Turn-off speed
Possible switch improvements
– For a given Rds(on):
– Reduced Eoss (stored energy in device Coss)
– Reduced Qg to enable faster switching
