Power supply apparatus for vehicles, has N-channel metal oxide semiconductor field effect transistor to perform switching of battery to load based on control signal from switch circuit driven by another battery

摘要

The output voltage from a battery (11) supplied to load (13), is controlled by N-channel MOSFET (15) which performs switching operation based on the control signal from switch circuit (19) driven by another battery (17). The batteries are distributed at rear and front of the vehicle. An independent claim is also included for power supply control procedure.
