Electric power supply device for motor vehicle, has regulator providing control signal to power generating circuit, and providing regulation characteristic so that sudden drop in operating voltage to minimum leads to rise in supply current

摘要

Device (10a) has power generating circuit (12a) providing supply current as function of control signal, and regulator (18a) to which reference signal and regulation signal corresponding to supply current are input to provide control signal to circuit. Regulator provides regulation characteristic so that sudden drop in operating voltage for electric loads to minimum leads to rise in supply current by 20% of maximum supply current by circuit. An Independent claim is also included for a method for provision of a supply current for electrical loads which can be operated at a rated voltage.
