Abstract
The disclosure provides embodiments of a self-contained automatic battery charging system having a power printed circuit board (PCB) that enables inputting an alternating current (AC) power flow to the automatic battery charging system. A first switchmode converter converts an AC input power to a direct current (DC) power, thereby providing an active power factor correction. The first switchmode converter comprises an isolation transformer, which provides an electrical isolation between a primary circuitry and a secondary circuitry of the automatic battery charging system. A second switch mode converter regulates a system output voltage and limits a system output current to an electrical load. A DC output is connected to a battery, another electrical storage device, and/or a parallel-connected DC load to be powered. An optional accessory PCB electrically connects to the power PCB and provides features including a liquid crystal display (LCD), alarm output relay(s), and/or a controller area network bus (CANbus) interface. The automatic battery charging system can implement a battery-life-extension charging regime. Other embodiments are disclosed.
