摘要： An inverter includes a three-winding transformer, a DC-AC inverter electrically coupled to the first winding of the transformer, a cycloconverter electrically coupled to the second winding of the transformer, and an active filter electrically coupled to the third winding of the transformer. The DC-AC inverter is adapted to convert the input DC waveform to an AC waveform delivered to the transformer at the first winding. The cycloconverter is adapted to convert an AC waveform received at the second winding of the transformer to the output AC waveform having a grid frequency of the AC grid. The active filter is adapted to sink and source power with one or more energy storage devices based on a mismatch in power between the DC source and the AC grid. At least two of the DC-AC inverter, the cycloconverter, or the active filter are electrically coupled via a common reference electrical interconnect.

摘要： A solid state power transformer is described for converting an input power signal at a first phase or voltage to an output signal of a second voltage or opposite phase by the use of bidirectional solid state switches switched at a high carrier frequency to produce a double-sideband, suppressed-carrier representation of the input power signal, which is then synchronously demodulated using further similar switches to produce the desired output. It is further disclosed that multiple instances of the above with relative phase-staggering of the switching frequency may be operated in parallel and activated or deactivated according to output current demand to provide maximum efficiency over a wide range of current and power levels.

摘要： A power conversion circuit uses a multiphase AC power source as an input and has a plurality of bidirectional switches each of which is connected to each phase of the multiphase AC power source. A switching control circuit controls the states of the plurality of bidirectional switches and switches a combination of two phases of the multiphase AC power source, relating to interphase voltage to be outputted from the power conversion circuit to a load side. A resonant circuit is connected to an output side of the power conversion circuit. The switching control circuit, at a time of switching of the combination of the two phases that output the interphase voltage to the load side, switches the states of the bidirectional switches relating to the switching, by soft switching.
