the current in the power transistor (Iprimary) is:
Lprimary: Primary inductance of the transformer
The advantage of primary current simulation is the elimination of the leading edge spike, which is
generated when the power transistor is switched on.
RZI (zero crossing input and primary regulation)
Zero current counter
Every time when the falling voltage ramp of V
zero-current-counter and increases the counter by one. If zero-current-counter and up-down-coun-
ter are equal the gate drive OUT is switched to high. Up-down counter is influenced via SRC voltage
as described below. If V
