A vector command generator generates vector commands that are respectively time integrals of voltage vectors and compose the difference command. A switching signal generator generates switching signals for controlling three pairs of switches in an inverter on the basis of the vector commands. A phase-current computing unit obtains an estimated value for the three-phase current on the basis of a current flowing DC buses and the vector commands. At least two of the vector commands that are time integrals of different ones of the non-zero voltage vectors have magnitudes greater than or equal to a predetermined value corresponding to a minimum required amount of time to maintain switching patterns in order for the phase-current computing unit to detect the current."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power converter controller","description":"A difference command generator generates a difference command equivalent to a time integral of three-phase voltage applied to an inductive load in a predetermined cycle in a complex plane.
