I need the clarification of output side of the transformerThis describes a similar supply.
On the secondary side there is also a rectifier diode. The output will not be pure DC, it cannot be, it will always have some ripple and some switching spikes. The filter on the output reduces this to some level acceptable for the circuit it was intended to power.I need the clarification of output side of the transformer
Transformer output one end (PWM signal) connected to CLC filter afer CLC filter we will get pure Dc output?
what purpose of Transformer other end connected Schottky diode cathode and snubber circuit?
secondary side Rectifying diode required?On the secondary side there is also a rectifier diode. The output will not be pure DC, it cannot be, it will always have some ripple and some switching spikes.

On the primary side, when the MOSFET switches off the drain voltage will rise above the supply voltage due to the inductive back emf from the transformer. The snubber circuit is there to protect the MOSFET from excessive voltage while wasting as little power as possible.
