The topology of the 37-kW quasi-direct ac-ac converter consists of a three-phase voltage source converter, a small plastic film capacitor and a three-phase voltage inverter. Two control boards, based on the dSMC (digital Smart Motion Controller) digital signal processor, were involved in the ac-ac system driving. They have been synchronizing through a fast serial link communication for real-time load power acquisition. The experimental test has been performed in order to show the ac-ac converter operation at distorted by 10% of 5-th harmonic supply line voltage.

Opisano quasi-bezpośredni 37 kW konwerter AC-AC składający się z trójfazowego źródła napięcia, cienkowartstwowego kondensatora i trójfazowego przekształtnika. Dwa procesory sygnałowe sSMC (digital Smart Motion Controller) włączono w układ sterowania. Ich rolą jest synchronizacja systemu napędu w czasie rzeczywistym. Eksperyment wykazał że jedynym zniekształceniem jest obecność 10% piątej harmonicznej.
