Product range
From float-cum-boost to SMPS and Li-Ion — built for harsh industrial environments.
Battery Charger, when used in stand by application is not a standalone dedicated Battery Charger. In standby application a Battery charger along with a floating Battery provide uninterrupted DC power supply to a critical DC load. This is Float-cum-boost battery charger or FCBC feeds the critical load without any break and also charges the discharged battery.

Battery chargers dedicated for charging Traction batteries are commonly known as “Traction Battery Chargers”. Traction batteries are used for material handling vehicles inside a plant, passenger carrying carts in airport or railway stations, Golf cart and similar applications.
Details
SMPS Battery Charger • A typical Switched Mode Power Supply incorporates a frontend AC-DC rectifier to generate an unregulated DC input voltage. • High power & high frequency MOSFETs/IGBTs then switches ON/OFF the unregulated input DC Voltage at a very high frequency (say 80Khz) at the primary of a ferrite transformer. • This high frequency ferrite transformer isolates, steps down and converts this square wave DC to square wave AC output. • It is then rectified & filtered to generate a smooth ripple free output DC voltage. • Pulse Width Modulation technique is generally employed to regulate the SMPS output.
