Abstract
An uninterruptible power supply (UPS) having an adjustable battery charger that generates a charger current, and a controller, coupled to the adjustable battery charger, that receives a signal representative of a system constraint and provides a reference, based on the signal, to the adjustable battery charger to control an amplitude of the charger current supplied by the adjustable battery charger based on the system constraint. The system constraint may include, for example, a maximum input current to the UPS, maximum charging current of the battery cell, and maximum and/or minimum charger current values.
