摘要： This power supply system for a D.C. electrical load, such as an illuminated sign, is normally energized by batteries. A central processing unit monitors the battery voltage and when it falls below a predetermined magnitude, the central processing unit then activates a starter motor which cranks an engine coupled to it. The central processing unit also actuates a valve and fuel pump to pass fuel to the engine. The engine drives an alternator which produces A.C. voltage which is then rectified by aa rectifier to recharge the batteries. When the batteries are fully charged the central processing unit stops the engine. The central processing unit employs a microprocessor chip to control operations of the system.
