Other Hybrid Innovations
Power Split Device
Splitting power produced by the gas/petrol engine between the drive train and the generator.
The power splitting device distributes the power produced by the gas/petrol engine to the drive train and to the generator. To divide the power efficiently, it uses a planetary gear consisting of a ring gear, pinion gears, a sun gear and a planetary carrier.
Employing synchronous A/C motor for compact packaging, light weight and high efficiency.
Toyota's hybrid technology uses synchronous A/C motors, which can efficiently produce strong torque up into the high revolution ranges and provide freedom to control motor revolutions and torque. Toyota has also succeeded in making electric motors more compact, light-weight and efficient, for smoother starts/acceleration.
The petrol engine used in Toyota hybrid technology is more energy-efficient, producing higher output than conventional petrol engines.
Power Control Unit
Toyota's hybrid technology is equipped with a Power Control Unit that consists of an inverter, a Voltage-Boosting Converter and an AC/DC converter to run the car on electric motors.
