Der Umrichter (3) umfasst mehrere Submodule (5a-5c), die eingangsseitig in Reihe über eine Induktivität (7) in einen aus einer Gleichspannungsquelle (4) gespeisten Versorgungsstromkreis (8) geschaltet sind. Jedes Submodul (5a-5c) weist eingangsseitig eine Halbbrücke (20) und ausgangsseitig eine mindestens einphasige Vollbrücke (21) auf. Die Halbbrücke (20) und die Vollbrücke (21) sind in jedem Submodul (5a-5c) jeweils zusammen mit einer Zwischenkreiskapazität (22) in einem Gleichspannungs-Zwischenkreis (25) parallelgeschaltet. Verfahrensgemäß werden die Submodule (5a-5c) im Wechsel auf den Versorgungsstromkreis (8) aufgeschaltet, indem die Zwischenkreiskapazität (22) des jeweils aufgeschalteten Submoduls (5a-5c) mittels der eingangsseitigen Halbbrücke (20) in den Versorgungsstromkreis (8) geschaltet wird.

    摘要: A DC to three-phase AC inverter system includes a three-phase motor, an inverter circuit, switching elements, a capacitor, a DC power source and a control circuit. The DC power source is connected to the three-phase motor at a neutral point thereof. The control circuit calculates voltage commands, first through third divided boost commands by dividing a boost command, and first through third drive signals based on the voltage commands and the first through third divided boost commands. The second and third divided boost commands are used when the PWM control is performed by turning on and off the switching elements for the second and third phases while the switching elements for the first phase continues to be on or off state is set larger than those used when the PWM control is performed by turning on and off the switching elements for the first through third phases.

    摘要: A primary-side DC voltage is increased to a secondary voltage by a converter (30c), and converted by an inverter (19) into three-phase AC, which is applied to an electric motor (10m). Regenerative power from the electric motor is reversely supplied to a primary-side DC power supply (18, 21).
    A secondary-side target voltage, which sets the secondary voltage to be applied to the inverter, is determined such that the electric motor is driven on the basis of one of a first region in a modulation mode in which PWM power is applied to at least two phases and in which field weakening control is not performed, a third region in a modulation mode in which PWM power at a voltage lower than a maximum voltage (Vmax) that can be output by the converter is applied to at least two phases and in which field weakening control is performed, and a second region ( FIG. 4 ) in a one-pulse mode in which rectangular-wave power at a voltage lower than the maximum voltage of the converter is applied to all the phases and in which field weakening control is performed. A converter control device (30v) controls the secondary voltage to the secondary-side target voltage.
