    Schematic with part numbers and values would be helpful.

    You need to appreciate the magnitude of the L/R time constant with respect to the switching frequency.

    Without a schematic, it is tough for us to provide you with anything but our best guess and well intentioned opinions.

    For these type of complicate questions u can not get the solution any where. u can get the solution by Mr. Muthukumaran, the SPMS DESIGNER.

    I think the vacuum tubes in the circuit are doing a good job by warming up in a time as short as only 450ms.

    Why do people talk about a circuit's problems and not attach its schematic??
