International Classification:

H02J 7/00
H02M 7/04

Abstract:

The disclosure provides embodiments of a self-contained automatic battery charging system having a printed circuit board (PCB) that enables inputting an alternating current (AC) power flow to the system. A first switchmode converter converts an AC input power to a direct current (DC) power, 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 system. A second switchmode converter regulates system output voltage and limits system output current to an electrical load. The 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 an LCD, alarm output relay(s), and/or a controller area network bus (CANbus) interface. The system may implement a battery-life-extension charging regime. Other embodiments are disclosed.

US Classification:

320107, 320137, 320162

Abstract:

There is disclosed in an embodiment, a charger having a PCB that enable input AC power to flow into the system. A first high frequency switchmode converter converts AC input power into DC power and to provide active power factor correction. The converter comprising a high frequency isolation transformer providing electrical isolation between primary and secondary system circuitry. A second high frequency switchmode converter connected to DC output from the first converter regulates output voltage and limits system output current. DC output is connected to a battery and/or other electrical storage device to be charged and/or to a parallel-connected DC load to be powered. An optional accessory PCB is electrically connected to the power board, housed in a same chassis or enclosure. The accessory board provides optional features including an LCD, alarm output relay(s), and/or a CANbus interface. Other embodiments are also disclosed.
