Detailed Solution
Download Solution PDF- A battery charger is a DC power supply source. Here a transformer is used to step down the AC mains input voltage to the required level as per the rating of the transformer.
- This transformer is always a high-power type and is able to produce a high current output as required by most lead-acid batteries.
- A bridge rectifier configuration is used to rectify the low voltage AC into DC i.e. Rectifier is a device that converts AC into DC and is further smoothed by a high-value electrolytic capacitor.
- This DC is fed to an electronic circuit which regulates the voltage into a constant level and is applied to the battery under charge, where the energy is stored through an internal process of the chemical reaction.
- In automatic battery chargers, a voltage sensor circuit is incorporated to sense the voltage of the battery undercharges. The charger is automatically switched OFF when the battery voltage reaches the required optimum level.
- Chopper is used to convert fixed dc to variable dc.
- Cyclo-convertor is a device that converts AC power at one frequency into AC power of adjustable but lower frequency without any DC current or DC stage in between.
