3 μs were assumed, Eq. 3 μs and T = 20 μs, Eq. 5b, efficiencies would lower. 5b it is assumed that at turn “on” the voltage across the transistor remains at its maximum value (Vdc ) until the on-turning current reaches its maximum value of Io . Then the voltage starts falling. To a close approximation, the current rise time Tcr will equal voltage fall time. Then the turn “on” switching losses will be P(Ton ) = Vde Io Tcr Io Vdc Tvf + 2 T 2 T also for Tcr = Tvf = Ts , P(Ton ) = Vdc Io (Ts /T). 5b), we may assume that current hangs on at this maximum value Io until the voltage has risen to its maximum value of Vdc in a time Tvr .
