I design a PWM system and use hspice (not pspice)
simulation tranformer ..
my system is boost and have 1 transformer + 1 inductor
and PWM chip will drive power MOS for transformer
and second side inductor will output DC12v
I use behavior model (like book ) but second side is not really have high volt ==> and how to really simulation transformer ??
and I find if I add "L" in system will have long time simulation
but behavior transformer don't need inductor ..
some Pspice book use L + KL and K =0.999 ..
and another problem is simulation have error on time_step too small ..
should I add some resistor in ideal inductor ??
