hi dear friends..
Im looking for some knowledge regarding a project I'm engaged in, relevant to power supply.
main aim of my project is to design a varaible voltage regulator which can be used with powered usb ports(usb pluspower) here are the basic specifications
input- 12V @ 3A (from poweredUSB port)
output voltage-5V to 30V (variable)
output current-1A all through out the range
I was first planing to use a buck-boost/cuk converter as output voltage is less or greater depending on the required output..But sepic topology seems to be like more straight forward as the polarity is not inverted...
So have you guys got any better idea or if you got any knowledge relevant to this kind of a project ur support is highly appreciated...
From basic reading what i understood was most of the times both these topologies are used to give a steady output when input is varying within a certain range..so I doubt how applicable those 2 topologies in to this perticular project..ur ideas are more than wellcomed.
thanks in advance...
