- Various semiconductor devices are utilized within the Hybrid Power Control Unit (HPCU) (the core component for controlling the hybrid vehicle), and these devices generate unavoidable heat when in operation.
- These devices are directly linked to high voltage, so their heat level is higher than the electrical devices found in a conventional combustion engine vehicle.
- Overheating lowers the efficiency of the control devices and limits proper operation control. In addition, the semiconductor can melt in extreme high temperatures (the devices are always turned ON) and such overheating causes failure.
