PWM Battery Chargers
High Efficiency, High Power, IGBT-based
Battery Chargers
MEGAMIC’s PWM Battery Chargers are based on latest technology using IGBTs in a Full
Bridge PWM topology. Operating from 3-phase (415 V) AC Supply input, they are
available in several kW Power levels. Compared to older technologies based on SCR,
these products offer Superior efficiency (85 – 90 %) and Lower Weight and Size.
They include the standard battery algorithms such as Constant Voltage (CV), Constant
Current (CC) charging profiles and other modes such as Float and Boost. These
algorithms can be customized according to the battery chemistry.
Other than 3-phase AC Supply input, the PWM Battery Charger can also be customized
to accept supply input from sources such as Generator/Alternator, Solar or Wind power.
A Fast Charger suited for e-vehicle Charging Stations is UNDER DEVELOPMENT, as
per ARAI standard.
