What are two main methods of rectification in aircraft electrical systems?

1. Diode rectification: Diodes are electronic components that allow current to flow in only one direction. In aircraft electrical systems, diodes can be used to convert alternating current (AC) to direct current (DC) by allowing current to flow in only one direction. This method is commonly used in small aircraft electrical systems.

2. Bridge rectification: Bridge rectifiers are electronic circuits that use four diodes to convert AC to DC. Bridge rectifiers are more efficient than single diode rectifiers and are commonly used in larger aircraft electrical systems to provide a more stable and reliable source of DC power.
