Bridgeless Boost Converter is used to convert the AC (Alternating Current) voltage to DC (Direct Current) voltage without using bridges. In normal boost converter only the variable DC voltage is converted to required DC voltage, but here AC is directly converted to DC.
There are three stages of charging a battery.
- Bulk Charging State: The charger provide constant current around 10% to 30% of the AH rating at 14.8V (AGM batteries). This stage is used to charge the battery to 80%.
- Absorption Charging: The charger provides constant voltage around 14.4 (AGM batteries). This stage provides the remaining 20%.
- Float Charging: The charger provides constant voltage of around 13.5V to 13.8V (AGM batteries). This stage maintains the battery at 100%.
