Abstract: <P>PROBLEM TO BE SOLVED: To generate a switching pattern that is superior in reduction of harmonic noise and the number of switching times in an AC-AC direct converter which controls a bidirectional switch by a spatial vector modulation system, using a control method of virtual DC link control system.  <P>SOLUTION: A switching pattern for switching a bidirectional switch selects the switching pattern of a zero-phase vector; such that one phase is invariant within an arbitrary switching period at all times and makes it undergo two-phase modulation. The duty cycle of a current/voltage spatial vector has an arrangement order so that two or more bidirectional switches are not switched simultaneously. The zero-phase vector is determined from input sector information, and the arrangement order is determined according to the parity discriminating information of an input sector and an output sector. The order of arrangement for duty command pulse is reversed for each update timing of a duty command.  <P>COPYRIGHT: (C)2008,JPO&INPIT
