Abstract: Provided is a matrix converter including a power converter, a commutation controller, and a compensator. The power converter includes a plurality of bidirectional switches. The commutation controller performs one of a three-step commutation operation and a four-step commutation operation by the bidirectional switches as a switch source and the bidirectional switches as a switch destination when an input terminal to be connected to an output terminal is switched by on/off control of the bidirectional switches. The compensator compensates for an output voltage error generated when the input terminal to be connected to the output terminal is switched, based on a potential difference before and after the switching of the input terminal to be connected to the output terminal, an output current of the output terminal, and capacitance between input and output terminals of unidirectional switches.

Abstract: A linear motor system includes a stator, a mover, and a controller. The stator includes a plurality of armature coil units arranged so as to be spaced apart from one another at certain intervals. The mover includes a permanent magnet. The controller is configured to sequentially select, as a power-feeding target, an armature coil unit opposing the mover from among the plurality of armature coil units, perform, for the power-feeding target, computation for power-feeding control on the basis of a speed command, and sequentially feed power to the armature coil unit. The controller includes a power-feeding-switching compensation function of performing switching compensation when the power-feeding target is switched to a next armature coil unit.
