HBL offers DSP controlled IGBT based Chargers which utiliz the latest state of art Space Vector theory with Pulse Width Modulation technology. This reduces the switching losses by limiting the switching to the two third of the pulse duty cycle. These chargers are built to provide constant DC source to the customer's critical applications as well charge the batteries. The Charger is of current limited type with two levels of charging the battery. These levels are float charging and boost charging levels which essentially designates the band voltage levels that can be set as per charging requirement of the battery. Output voltage regulation is achieved by controlling the IGBT. The charger can provide constant voltage power to the load with simultaneous boost charge to the discharged battery. The current limit can from 10% to 90% of the charger output capacity.
