Does the car charge a battery in its own (12V) does not also need a rectifier? To their own spark plug ignition is not "rectification" to ten thousand V? So, in the generator and then a head, rectified to 48V not work? Ask the teacher. Does the car charge a battery in its own (12V) does not also need a rectifier? To its own spark plug ignition is not "rectification" ...
General car engine around the limited space, and then installed 48v generator I am afraid there is no space, say there is no power out of the equipment, if there is space, and then have power out of equipment, you can install another set of power generation equipment. But he and the car generator power supply system is completely unrelated to another set of power generation equipment. Such as power generation is too large, will affect the engine power.
First 12 volts AC into 48 volts AC, which is easier. And then the rectifier will be 48 volts AC into DC. As for the power, I believe the user can master. Because even a 12-volt power supply, there is also a power problem.
You said the car in the battery to charge its own (12V) is a rectifier. But can not put the 12-volt alternator, the power of the "rectifier" to 48 volts, rectifier: only the generator AC, through the rectifier into a DC charge into the battery, and can not be boosted to 48 volts, say the load is too large On the generator is influential, and its power is limited, can not be changed.
