Exro’s Dynamic Power Management technology
For almost two centuries, electric motors and generators have used technologies that only operate efficiently in limited circumstances.
The Exro DPM technology is a control system that integrates wiring of the rotating machine coils into the power electronics. This gives the power electronics control of the machine coil wiring configuration in real time, providing a range of options in place of a fixed machine configuration.
The control system will select the best configuration for a given operating condition using an application-specific algorithm. Exro’s breakthrough approach to generator and motor design and control improves efficiency across highly variable input and output applications. Until today electric machine coils have been wired in a single configuration and the designer had to select the configuration that is the best compromise over the range of operating conditions. DPM senses input energy and load, and seamlessly switches coil wiring in any combination from full parallel to full series.
In essence, DPM provides voltage control with multiple performance curves corresponding to the coil configurations in the electric machine. Exro’s technology is designed and built into our partner’s electric machine and power electronics for the application. DPM is fully integrated with the power electronics design; there is no separate hardware package.
