要約(英語): This paper discusses a new power flow controller consisting of six cascaded converters. Each cascaded converter is composed of four series-connected H-bridge converters, and connected between one phase of the three-phase terminals at the sending end and another phase terminal at the receiving end. Each converter controls its current to be orthogonal to its voltage, and injects a reactive power into the grid. Then the average voltage across the dc capacitor can be kept at a constant level, because no active power is drawn from the grid to the converter. The new power flow controller can adjust not only the reactive power flow but also the active power flow by controlling only the reactive power through the six cascaded converters, because the converter voltage is shifted by ±30° from the phase voltages at the sending and receiving ends. Experimental results obtained from a 400-V, 10-kVA downscaled setup using twenty four H-bridge converters show the capability of controlling both active and reactive power flows as well as regulating the dc capacitor voltage.
