Transportation Systems
The auxiliary power supply (static inverter) converts the power for interior light, displays, air conditioning, etc.
Even though there is a propulsion inverter, the static inverter is installed in order to supply power that has low voltage and constant frequency.
The propulsion inverter provides for smooth ride comfort while the static inverter provides for interior comfort.
