    摘要: A power converter is provided for direct conversion of multi-phase AC power to AC power. The power converter includes a conversion circuit, a plurality of input lines and a plurality of capacitors. The conversion circuit has first and second switching elements that are configured to be connected to the phases of the multi-phase AC power for bidirectional switching of energizing current. The input lines are connected to the conversion circuit. The capacitors are connected to the conversion circuit. The first and second switching elements are arranged such that paired input terminals line up in a row with the paired input terminals to an outside, and paired output terminals to an inside. The input lines extend in a direction in which the paired input terminals line up, and extend from one of the input terminals to another of the input terminals.

    摘要: A three-phase inverter includes three series circuits that are connected in parallel to a capacitor connected in parallel to a DC voltage source. Each of the three series circuits includes two semiconductor switching elements connected in series. A connection point between the two semiconductor switching elements is used as an AC output terminal for each phase. The three-phase inverter generates PWM pulses of three phases including a PWM pulse of one phase, whose pulse width of a positive side pulse in one switching cycle is the largest, and including PWM pulses of the other two phases such that a positional relationship between positive side pulses of the other two phases is a positional relationship in which an overlapping range on a time axis is smaller as compared with a state in which a positive side pulse of one phase encompasses a positive side pulse of the other pulse.

    摘要: Provided is a power converter 3 that directly converts polyphase AC power to AC power. A converter circuit has a plurality of switching elements 311, 313, 315, 312, 314 and 316 which are connected to each phase R, S or T of the polyphase AC power to enable switching for turning on current-carrying bidirectionally. At least three condensers 821 to 826 are provided between phases of the converter circuit. The three condensers are respectively placed at apexes of a triangle on a plane that is in parallel with a part-mounting surface on which the switching elements are actually mounted. The wiring distance between the condensers and the switching elements can be shortened.
