I am currently designing a power conversion system for an EV. The system must power a number of electronic devices all running at around 12V, this is where my issues begin.
The accumulator system thats being used operates at around 230VDC. I must step this voltage down to 12V, but have found it to be a far more difficult task than intended. There aren't any DC-DC Converters out there that perform such a large step-down, so I've been looking into other methods, including the use of a 48V-12V converter and using a resistor network to stepdown the voltage so the DC-DC can use it effectively. Im not looking at a massive power conversion here, I only need around 250W of power for the electronics im powering. Any help or insight into this would be greatly appreciated. I would like to note that I must use the accumulators to power the GLV electronics, therefore I must use a converter of some sort.
