This equation defines the diode voltage curve: vd=vR−(vR−vRM)exp(−(t−t1)/τrr), (17)where vRM=vR−iRM(R−Lτrr) is the maximum diode reverse voltage. If Lτrr≫R, which is a common condition for the reverse recovery test circuit, the block calculates the maximum ...

During 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. iF+at=qE−qMTM(4)

It allow...
This equation then defines the value of the diode current: where: i is the diode current. qM is the total stored charge. Qscale is the current value of the charge ratio.Temperature Dependence The default behavior for the Diode block is that dependence on temperature is not modeled, and the...
a phase-shifted ZVS full bridge DC/DC converter Introduction The ZVS exploits the parasitic circuit elements to guarantee zero voltage across the switching device before turn on, eliminating hence any power losses due to the simultaneous overlap of swi...
I'm confused about whether zener is on or off due to not being able to know voltage on V0. I tried to find by applying KCL & KVL, but current on the diode (Id) and the resistor (Ir) is not equal to each other. I'm using the shockley diode equation.(Id=Is...
