What is the electrical output of the inverter used for in the B car?

The electrical output of the inverter in the B car is utilized primarily for air compressor operation. The inverter converts DC power from the train's power source into AC power that is necessary to run the air compressor effectively. The air compressor is a crucial component of the air brake system, as it generates the compressed air needed for braking. Without sufficient air pressure from the compressor, the air brake system would not function properly, leading to decreased performance and safety concerns during operations.

This understanding highlights the importance of the inverter's role in powering essential system components, ensuring that the train operates smoothly and safely.
