Design and Development of PC-based Smart Programmable Power Supply for Battery Charging System.

The rapid growth of renewable energy sources and the demise of fossil fuels are causing rapid growth of battery application. The lifespan of battery is expected to be long and it is affected by battery charging and discharging. When charging battery, the charger must consider battery type, voltage and temperature. Smart programmable power supply is implemented as battery charger which has flexibility to adjust different parameter such as battery type, nominal voltage, current limit and temperature limit. The smart power supply is reconfigurable by virtual instrument software in personal computer (PC). The smart power supply has voltage range 1.4 to 22 V with 0.1 V resolution and maximum current 2 A with 0.1 A resolution. [ABSTRACT FROM AUTHOR]
