A method for operating a matrix converter that includes converting m phases of a generator into alternating voltage with n phases of a load connected to a network, wherein n<m. The n phases of the load are alternatingly connected via a multiple number of controllable bi-directional switches arranged in an (mxn) matrix, whereby n phases of the generator are always connected with the load while (m-n) phases of the generator are not connected with the load. The matrix converter may be used for at least part of the start-up process, in particular for the initial part of the start-up process of the generator reversely operating the matrix converter in cycloconverter mode using power available from the network, wherein the group of m phases of the generator are grouped in corresponding subgroups.
