NCP1216 Flyback universal mains adapter
Created by ICAP4Designer, published on 17-05-2013
the NCP1216 is a PWM current mode controller, it can work at 65, 110, 135 khz. This model features a ramp compensation to prevent oscillations from taking place in continuos conduction mode. A ramp setting resistor in series with the pin CS controls the amount of ramp compensation required. SPICE simulation of transient and AC model.

Forward Converter with Settable Saturable Transformer
Created by NiMultisimDesigner, published on 12-05-2013
In the first transient SPICE simulation the transformer core is set as linear and not saturable core described by a 50uH inductor. In the second simulation is set a dependence of the magnetic flux versus the current so that the inductance changes from 50H to 5H at 5 Ampere, The transistors currents are very high and may damage or destroy the real circuit.
