Forward converter



CASPOC Schematic

Components

This converter is designed with an Vin=360V
Desired out Vout=24V

Single MSFET driver which should handle voltage which is equal to 2xVin.
Based on the buck converter with Inductor L11 connected in series with the capacitor C1.
Load resitor R1
It offers isolation from by using a transformer. The forward converter has the transformer with the reset windings with the diode D3 to maintain flux continuity when the switch is OFF.
Np=Nreset
Ns is dependent on weather you are stepping up or stepping down the voltage.

Questions and remarks

It is assumed :
Buck converter operates in the steady state
Buck converter operates in continuous model

SCOPE 1:
Dark blue gragh ---> represents the Voltage output
Red gragh ---> current measurement across the Inductor

SCOPE 2:
Represents the current across the capacitor
