WebbDuring initial current drop in reverse mode, the diode is still on, and the rate of change of current is determined by an external test circuit. First, the block uses equation 1 to perform this calculation. i F + a t = q E − q M T M (4) Then, it substitutes equation 4 into equation 2. d q M d t + q M τ = i F + a t (5)

WebbA high output current also introduces a high di/dt on the rectifiers. For high efficiency, the choice of MOSFET is mainly determined by the on resistance and the gate charge.
