Project abstract

The project investigates the possibilities of using a combination of power electronics and a mechanical switch to obtain the benefits of both components.

Power electronics provide controllability and possibility to interrupt or commutate currents in some micro seconds. The drawback of power electronics are high on-state losses both considering cost and increased complexity since cooling systems are needed. One way to solve it is to put a mechanical switch in parallel to the power electronics to carry the nominal current. The switch never has to interrupt any current, only commutate the current over to the power electronics and hence it can be made lighter and faster than a circuit breaker. The project investigates the development of such a commutation switch considering the issues of fast current commutation and mechanical endurance.


Summary of work

A new switching laboratory has been designed and built at KTH, with the main focus on testing high speed actuators and current commutation.

2015. The laboratory has been functioning since 2015. Initial tests on current commutation have been performed and published in a conference paper. The lab prototype has been used for testing, and redesigned and improved during the year; testing on current commutation has continued, and was finalized during the end of 2015.

2016. A new prototype was designed and built during the first half of 2016 and installed in the lab after the summer. Tests are ongoing with commutation of larger currents and will be finalized by the end of the year.

2016. During the second half of 2016 an improved prototype has been tested; the work is ongoing to perform and validate the most important design parameters for the mechanical commutation switch.

2016. A software on optimization of the switch design parameter has been developed and delivered to ABB via the Innoenergy project ESPE in which this PhD project was active during 2016. A publication on the results is underway at the end of 2016.
