摘要： Methods and apparatus to provide low harmonic distortion AC power for distribution by converting energy from natural or renewable sources into electrical form, and constructing a current waveform on a primary winding of a transformer by recapturing inductive energy previously stored in the transformer so as to transform the converted electrical energy into substantially sinusoidal AC voltage at a secondary winding of the transformer. For example, AC power may be supplied to a utility power grid from raw electrical energy from renewable energy sources (e.g., solar cells). An inverter may construct the primary winding current waveform using two unidirectional switches. On each half cycle, one of the switches first applies energy previously recaptured from primary winding inductance, and then applies the raw energy to the transformer primary winding at the utility power grid frequency. Accordingly, the constructed primary winding current may exhibit substantially improved total harmonic distortion.

摘要： In a multilevel converter (3), three circuit breakers (B11 to B 13) are respectively connected between three arms (A1 to A3) and three reactors (L11 to L13). One circuit breaker (B 11) is a DC circuit breaker configured to interrupt direct current when a short circuit accident occurs between two DC power transmission lines (1, 2). Each of the two circuit breakers (B 12, B 13) is an AC circuit breaker configured to interrupt alternating current when the short circuit accident occurs. When the short circuit accident occurs, the two AC circuit breakers (B12, B13) are brought into the non-conductive state and then the DC circuit breaker (B 11) is brought into the non-conductive state, thereby interrupting the short circuit current.

摘要： A power output apparatus includes first and second motor generators, first and second inverters and a relay circuit. The first and second motor generators include first and second 3-phase coils, respectively. The first inverter alters periodically the potential at a first neutral point of the 3-phase coil. The second inverter alters periodically the potential of the second neutral point of the second 3-phase coil at phase corresponding to a phase-inverted version of the potential change of the first neutral point. The relay circuit responds to a control signal from the control device to electrically connect first and second AC lines to a connector, and provides an alternating voltage generated across the first and second neutral points to the connector.
