Hello,
We have just been asked to do a 300W SMPS for electric vehicle, input is the vehicle battery, which is 300-410VDC, and the output is to be 15V. Why is the output so low in voltage? The only reason petrol cars have a 12V system is because that’s the typical voltage of a lead acid battery with a few cells.
Why aren’t we being asked to provide a more practical voltage output like 42VDC?
