simuler une alimentation flyback sous pspice
Hello,
I am trying to simulate a flyback switch mode power supply. i have ONLY the PWM controller chip UC1844A and associated circuitry. i try to first see this device switching, 50% duty cycle. then, when that works, i move on to model rest of circuit.
but i can not get UC1844A to simulate at all without causing Convergence errors!!
has anyone ever tried to use this device, or SG1844 , in a PSpice circuit and is willing to reveal how they got it to work??
Thanks,
Mr.Cool
