Abstract
A load-commutated synchronous motor drive has a line-commutated network-side converter (3), a current-source dc intermediate link (PL, NL, 5) and a load-commutated machine-side converter (2) for connection to a synchronous machine (1). The motor drive comprises control members adapted, to ensure the commutation, in connection with commutation of the machine-side converter (2), to switch the network-side converter (3) for operation with a lower pulse number than the natural pulse number of the network-side converter.
