Looking for design help. Answered
I want to build a dc-dc converter with input voltage from 10 to 30 volts and output of 13.5 at 400 watts. This is so I can power a 400 watt inverter from 2 batteries on my camper... I am frustrated with the inverters shutting down at 11 volts saying dead battery, and this way I would be able to drain the 2 down to 5.5 volts each before that happened to me. Hopefully there is a simple answer for this, I am not to keen on the idea of $400.00 to purchase the only one I found on the net.
