Ultra high speed inverter
Prodrive technologies is developing a high speed inverter. The motor and inverter combination will be able to handle speeds greater than 100.000 rpm. There are many automotive applications, amongst others electric turbochargers, range extenders and fuel cell compressors. Besides the applications in figure 1, Prodrive Technologies is open to discuss other functions.
Prodrive Technologies offers inverters for high-speed electric machines and provides engineering support for rotor/stator design and mechanical integration with the customer’s application specific system as visualized in figure 1. Prodrive Technologies has preferred partners for these applications, but it is also possible to cooperate with partners proposed by the customer.

Electric turbochargers and compressors for combustion engines
The high speed inverter and electric motor can be integrated into a turbocharger or compressor. This reduces turbo lag and improves drivability, emissions and fuel efficiency of the vehicle.
Turbine range extender
By integrating the inverter and electric motor with a turbine, we are able to offer range extender solutions for electric vehicles. Advantages of the turbine range extender over a combustion engine range extender are greater power density, multi-fuel capability, low emissions, low maintenance and less (moving) parts.
High speed air compressor for fuel cell applications
When powering a vehicle using a fuel cell, the fuel cell needs to be kept at a specific pressure in order to operate optimal. A compressor with a high speed motor can handle the required highly dynamic behavior whilst providing the required air flow and pressure. The electric motor can be integrated.
