Quick response high power cycloconverter-drive controlled by fully digital multiprocessor-system

The most reasonable cycloconverter operates without circulating current. There are importance of shortest current zero periods is shown. At the same time highest requirements on dynamic behaviour have to be achieved with fully digital control. By use of multiprocessor structure the dead times can be reduced to a minimum if the interfaces between the tasks of the several processors are designed carefully. It is shown, how this can be done in an optimal way
