ePowerHub
The ePowerHub enables research and education of electric machine and power-electronic converter technologies that are essential for wind turbines, solar photovoltaic plants, hydrogen systems, electric vehicles, electrified working machines, and many other applications.
Equipment
Our 230 m² of laboratory space includes state-of-the-art equipment dedicated to the research and education in:
- electrical machines and drives
- power electronics
- integration of renewables into the electric grid
- characterisation of magnetic materials
The laboratory can accommodate large and heavy machinery up to 200 kW. The laboratory encompasses a digitally configurable and scalable power supply system (up to 750 kVA, 400 A) covering a frequency range from DC to 400 Hz. Furthermore, the laboratory is equipped with bidirectional programmable 50-kVA AC and DC power supplies that can be used, e.g., to emulate electric grid or batteries as well as to test electric machines and power converters.
The ePowerHub also includes equipment for magnetic material characterisation, with supply frequency up to 50 kHz and various data acquisition devices with sampling frequency up to 1 MHz. This characterisation unlocks the potential of our researchers to develop accurate simulation tools for energy conversion components.
For developing advanced control methods for electric machine drives and power electronics, the laboratory is equipped with several high-performance rapid-prototyping systems.

Research groups
The following four research groups work in the ePowerHub facilities. In addition to research, we offer hands-on teaching of energy conversion devices (machines, drives, power electronics) for master's and doctoral students in the field of electrical engineering and automation.
Where to find us?
The laboratory facilities are located on the Otaniemi campus at Puumiehenkuja 5.
