Jaguar I-Pace accelerates with sintered IGBT chips
When the driver of Jaguar's electric racer I-Pace steps on the accelerator pedal, he floods the engines with a current of up to 650 amps. The control system comes from supplier Continental. The company has now provided an insight into the underlying technology.

In contrast to combustion engines, electric drives develop their maximum torque right from the start. The fascinating acceleration associated with this is one thing, another one is the question of how to control such powers and the associated extreme load changes. Continental has developed a system solution for Jaguar Land Rover that is specially tailored for sporty high-performance drives. It is designed for the entire JLR electric fleet and will be used in all future electric models of the British manufacturer. This power electronics module is also used in Jaguar Land Rover's Plug-in Hybrid Rover Sport.

In hybrid and electric vehicles, power electronics are a key component of the electric drive. It supplies the electric motor with power and also controls energy recovery (recuperation). Functionally, it therefore stands between the high-voltage battery and the electric motor. Since the battery delivers direct current but the motor requires three-phase alternating current, the power electronics converts the current accordingly by means of an inverter and passes it on to the motor, which is controlled via these parameters, in the required strength and frequency.
