System Outline: Inverter

* The inverter converts the high-voltage direct current from the HV battery into three-phase alternating current for driving motor generator no. 1 and motor generator no. 2.

* The activation of the power transistors is controlled by the HV ECU. In addition, the inverter transmits the necessary information for current control, such as the output amperage or voltage, to the HV ECU.

* Along with motor generator no. 1 and motor generator no. 2, the inverter is cooled by the exclusive radiator and coolant system which is separated from that of the engine.

* In a vehicle collision, the circuit breaker sensor installed in the inverter outputs the collision signal to stop the system.

* A boost converter has been adopted in the inverter, which increases the rated voltage output from the HV battery from DC 201.6V to DC 500V. After increasing the voltage, the inverter converts the direct current to alternating current.
