A powerful example of our journey from racetrack to road, the MPU-200 builds on our many years of experience in developing inverters using advanced materials to achieve low-weight, high-efficiency and race-winning power in Formula 1 and Formula E.
The inverter sits at the heart of the electrified powertrain, acting as the control junction between the battery and the motor, transforming DC (Direct Current) voltage from the battery into an AC (Alternating Current) supply for the electric motor, for which the inverter also fulfils all the necessary safety functions.
The MPU-200 inverter uses silicon carbide (SiC) technology which enables a significant increase in switching frequency, therefore allowing the use of faster, more efficient and lightweight motors. Optimised switching methodology increases efficiency and further reduces mass, giving greater range and improving car performance.
Silicon carbide inverters offer considerable efficiency gains versus conventional inverters based around silicon semiconductors because they produce less heat and are less temperature-sensitive, and therefore have lower cooling demands. They also occupy a smaller form factor, making them ideal for use in electric vehicles.
The MPU-200 is designed to lie at the very heart of a variety of mobility solutions and conforms to all the relevant automotive industry standards including ISO26262 and ISO6469 while retaining a class-leading power-to-weight ratio.
It’s a simple case of mathematics: greater efficiency improves range, cuts charging times and can reduce the cost of batteries – key virtues that can provide a race-winning advantage in motorsport and drive customer uptake of electric vehicles in the wider automotive space.
