Voltage Converter: Description and Operation
ENGINE CONTROL COMPONENTSVariable Voltage Controller
The variable voltage controller is located within the transaxle. The variable voltage controller is a bi-directional voltage boost converter that couples the high voltage traction battery to the transaxle's generator motor and traction motor. The variable voltage controller steps up voltage output to maximize motor and generator efficiency. If there is a concern, the transaxle control module (TCM) will bypass the variable voltage controller and set a diagnostic trouble code (DTC).
