IGBT-based battery charger Battery chargers play an important role in ensuring the optimum life and performance of industrial storage batteries. Enertech chargers have been doing the job tirelessly in various power plants, substations, steel mills, refineries, petrochemicals, cement plants, oil and gas pipelines, telephone exchanges, and many other industries for the past 30 years.

The main function of the industrial battery charger is to provide a constant DC load and charge the battery bank according to the user’s requirement. In the event of failure of the main AC supply, the battery bank supplies the constant and emergency D.C load.

The AC power to DC power conversion element is usually configured in the system from a thyristor or switch-mode technology depending on the application, criticality, and space availability. Thyristor-based systems are very robust and suitable for the most demanding environmental and operational conditions.

1. Single Float Cum Boost Charger

This is a special type of low cost charger for the low voltage range. Only one converter is used. In floating mode, it connects directly to the charging bus and simultaneously floats the battery to meet the DC load at a constant voltage. In boost mode, the battery will be charged at a constant current rate. The load will be connected by a controlled dripper so that it is not affected by the charging (charging) voltage. In this system, simultaneous floating and impulse charging can be done with a single converter.

2. Float Charger + Float Cum Boost Charger

The system consists of two converters for Float loader and Float cum Boost. The main function of a floating charger is to provide a connected DC charge and to simultaneously charge the floating battery bank to keep it in a fully charged state so that it can charge the charge during a power failure or a power problem. input power supply. The function of the Float charger is to quickly charge the battery after a heavy discharge and return it to full capacity in the shortest possible time and to charge the charge if the Float charger fails.

3. Dual Float Cum Boost Charger- Single Battery -Single load

The floating charger is connected directly to the charging bus and the Boost charger is connected to the battery. The floating charger will provide a continuous load at a constant voltage. The Boost charger will quickly charge (increase) the discharged battery at constant current as needed. A DC (DC) contactor is connected between the battery and the charging bus. It will connect the battery to charging when charging is complete or the float charger is damaged or the AC power source is damaged. The take-up time (200-500ms) of the DC contactor may interrupt the charge. The connected cell blocking diode (CD) provides at least 80% of the battery voltage during this time.

4. Dual Float cum Boost charger - Two Battery - Single load

The system consists of two converters for Float loader and Float cum Boost. The main function of a floating charger is to provide a connected DC charge and to simultaneously charge the floating battery bank to keep it in a fully charged state so that it can charge the charge during a power failure or a power problem. input power supply. The function of the Float charger is to quickly charge the battery after a heavy discharge and return it to full capacity in the shortest possible time and to charge the charge if the Float charger fails.
