Control of a matrix converter in the saturation area of the output voltages

A matrix converter (1, 1A, 1B, 1C) according to the embodiments includes a voltage command corrector (22, 22A, 22B) and a drive signal generator (23, 23A). The voltage command corrector (22, 22A, 22B) corrects the magnitude of an output voltage command (Voref1, Vuvwref1) on the basis of amplitude va...

Beschreibung
Zusammenfassung:	A matrix converter (1, 1A, 1B, 1C) according to the embodiments includes a voltage command corrector (22, 22A, 22B) and a drive signal generator (23, 23A). The voltage command corrector (22, 22A, 22B) corrects the magnitude of an output voltage command (Voref1, Vuvwref1) on the basis of amplitude variations of an input current from an AC power supply (2) to a power converter (10), the amplitude variations being caused by a ripple component (Idstest) of the input current. The drive signal generator (23, 23A) generates drive signals (S) that turn ON/OFF a plurality of bidirectional switches (Sru, Ssu, Stu, Srv, Ssv, Stv, Srw, Ssw, Stw) on the basis of the output voltage command (Voref1, Vuvwref1) corrected by the voltage command corrector (22, 22A, 22B).
