Within the framework of the IEA 4E Electric Motor System Annex, Switzerland is co-managing the two work packages "International Standards" and "Testing".
The Task "International Standards" organizes the activities of EMSA members in the technical committees for international standards, namely in efficiency related working groups for electric machines and converters in IEC. In order to be ready to present a reliable testing method for converter losses and to review the currently defined reference losses and efficiency classes, EMSA in cooperation with IEC has launched an international Round Robin testing program for converters losses (RR'C).
In the task “Testing” Switzerland, together with Denmark, is responsible for the organization, monitoring and documentation of the Round Robin test program for converter losses.
