In certain transport aircraft using AC electrical power, how are batteries kept charged?

In transport aircraft that utilize AC electrical power, the batteries are kept charged through rectifiers using AC generators. This process involves converting the alternating current (AC) produced by the generators into direct current (DC), which is necessary for charging the batteries.

AC generators produce electricity that can be used to power various systems in the aircraft. However, since batteries require DC for charging, rectifiers serve as the crucial components that facilitate this conversion. The rectification process ensures that the electrical energy generated by the AC generators is properly conditioned to match the requirements of the batteries.

This charging method is essential for maintaining the batteries' charge levels, ensuring reliable performance of onboard systems and emergency power capabilities when needed.
