Switch Mode Chargers for UPS

A switch mode (SMBC) battery charger converts alternating current (AC) to Direct Current (DC). Switch mode chargers are faster, smaller, lighter, and more efficient than equivalent linear battery chargers. Designing a battery charger with switching converter topologies to charge battery packs has considerations with regard to the required charge-current level, AC adapter voltage level range, the expected ambient temperature range, and the desired converter switching frequency. The buck converter topology is most often used for switch mode chargers in either synchronous or non-synchronous modes.
