Starting inverters

For refurbishing power stations we design and supply starting inverters for gas turbine sets with approx. 4 MW and large hydro turbine sets with a starting output up to 20 MW.

For multiple alternator plants we supply commutation gear, so that one starting inverter can start e.g. 3 alternators.


Power electronic equipment for control of motor and alternator in pump storage plants

The following picture shows a 10 kV inverter for a synchronous alternator of 21,3 MW for reequipment of a pump storage plant. This 6-pulse inverter with intermediate circuit with constant current makes it possible to control the speed of a machine set with primary and secondary control of the line.
