0-300 V 0-500mA Power Supply

[garg29]

Hi,
guys I'm in a need to design a power suuply with a rating :- 0-300V 0-500mA DC, adjustable. I just need the basic idea & how to startup. I have already referenced to below given link (but the current is, low & non-adjustable)


Any better idea. I have to adjust the Voltage & Current with microcontroller but that's a 2nd issue.

Regards.

I'm having a readymade - similar kind of power supply. The user is using KA3525 SMPS CONTROLLER. I want to understand how the user is controloling the current & voltage
