    摘要： A pulse pattern generating configuration for a three-phase current source electric power converter is provided that ensures a minimal switching loss regardless of the level of power factor, and thus improves the electric power conversion efficiency.When an inter-line voltage non-maximum phase (U-phase) and a line current command value maximum phase (U-phase) match one another, in one modulation period T, a separation time T1 is established to separate, in time, switching pulses of two phases (V-phase, and W-phase) other than the line current command value maximum phase, and a short-circuit pulse SP is disposed in the line current command value maximum phase (U-phase). When the inter-line voltage non-maximum phase (V-phase or W-phase) and the line current command value maximum phase (U-phase) do not match one another, in the one modulation period T, the switching pulses of the two phases (V-phase and W-phase) other than the line current command value maximum phase are disposed next to one another in time, and the short-circuit pulse SP is disposed in the inter-line voltage non-maximum phase (V-phase or W-phase) or in the line current command value maximum phase (U-phase).

    摘要： A power generation system is provided that implements an efficient, labor-saving system interconnection in which an engine generator system, an external power supply system, and a capacitor are connected in parallel to each other, without the conventional practice to change the configuration of the engine generator system or provide an additional circuit. A power generation system implements a system interconnection in which an engine generator system, an external power supply system, and a capacitor are connected in parallel to each other. The power generation system includes discontinuing means for discontinuing direct-current voltage control by which a direct current voltage of the capacitor is controlled when electric power from a generator is supplied to the capacitor while direct current electric power that an external power supply supplies is lower than demand power that a power generation system is supposed to supply.

    摘要： An electrically-driven work machine can exchange electric power between a storage battery and an electric power system or between the storage battery and a load by utilizing an inverter equipped therein. When electric power is exchanged between the storage battery BT and the electric power system PW or the load, the connection between the inverter INV and the storage battery BT is disconnected by an on-off switch S0. Further, by change-over relays RY1 to RY3, one of AC phases from the inverter INV is connected to a wire LC1 via a DC inductor Ldc, and the other two phases are connected to the electric power system PW or the load via AC inductors Lac. When a motor Ma is driven by the storage battery, the on-off switch S0 provides a connection between the anode or cathode of the inverter and the storage battery BT.
