Document Type and Number:
Japanese Patent JP5880628
Kind Code:
B2
Abstract:
Disclosed is a matrix converter (1) that directly converts input three-phase AC power into three-phase AC power and outputs the converted three-phase AC power to a load (LD) . The matrix converter includes: a bidirectional switch circuit (10) that switches on or off the supply of the three-phase AC power to the load; and a controller (20) that performs different virtual AC/DC conversion processes according to a plurality of modes which are divided depending on magnitude correlation between respective phase voltages in the input three-phase AC power, with respect to the input three-phase AC power, selects two phases from the input three-phase AC power, and generates switching patterns of the bidirectional switch circuit so as to perform the different DC/AC conversion processes according to the plurality of modes with respect to line voltages of the two selected phases.
