Description
The inverter converts the boosted high-voltage direct-current from the HV battery into alternating current for MG2 and MG1. The inverter generates heat during the conversion process, and this heat could damage the inverter if a inverter cooling system is unavailable. Therefore, similar to MG2 and MG1, the inverter is cooled by a special inverter cooling system consisting of an electric water pump, cooling fan, and sub radiator. This inverter cooling system is independent of the engine cooling system. The hybrid vehicle control ECU monitors the electric water pump, cooling fan, and inverter cooling system, and detects malfunctions.
