Hi,
i would to like understand the Importance of auxillary winding..
Does it really needs..
It can drive from the Direct DC Bus Voltage (Bulk capacitor) then why it cant..??
Also the device is rated for the 725 voltage..
i obseved the Peak voltage at the drain is almost 635V..
But the Bulk capacitor i used having capacity of voltage of 400V.
doesnt it cause high voltage spikes of drain and get burst..??
Can anyone guid me on the same.

Attached is the circuit..
