    摘要： A protection device for a power converter provided between an AC system and a DC power transmission system is configured to: receive an input of an AC current value obtained between a transformer connected to the AC system and the power converter capable of converting AC power into DC power; receive an input of a change rate of a direct current detected by a Rogowski coil provided between a DC line and the power converter, the DC line receiving DC power from the power converter; determine based on the AC current value and the change rate whether a fault occurs or not in one of the power converter and the DC line; and output information for protecting the power converter based on a determination result.

    摘要： A voltage converter system includes a first DC-AC voltage converter that converts a first DC voltage signal to a first AC voltage signal. A DC link converts the first AC voltage signal to a second DC voltage signal. A second DC-AC voltage converter converts the second DC voltage signal to a second AC voltage signal. In another configuration a DC-AC voltage converter converts a DC voltage signal to a first AC voltage signal. An AC-AC voltage converter converts the first AC voltage signal to a second, lower-frequency AC voltage signal. In yet another configuration a first voltage converter portion converts a DC voltage signal to pulses of DC voltage. A second voltage converter portion converts the pulses of DC voltage to a relatively low-frequency AC voltage signal. The voltage converter system is selectably configurable as a DC-AC voltage converter or an AC-DC voltage converter.

    摘要： This invention relates to electrical aircraft engine start and generating system for use in an aircraft having an engine driven torque converter coupled to an alternator which provides AC power for conversion to DC and AC power. The system includes a reversible AC to DC converter controllably electrically coupled to the alternator and a controller unit to provide DC power in a generating mode. The reversible AC to DC converter is capable of receiving externally supplied DC power to be converted to AC power to drive the alternator as a motor in a start mode. A DC to AC converter is controllably electrically coupled to the controller unit and the DC power output during the generating mode. The reversible DC to AC converter in the start mode is mutually controllably electrically coupled to the externally supplied DC power. The controller unit and the alternator cooperate to provide a controlled AC power output to be delivered to the alternator to bring the alternator operating as a motor up to operating speed, whereupon the reversible DC to AC converter responds to the external DC power and is electrically coupled to the alternator to drive the alternator as a motor to deliver rotary power through the torque converter to start the aircraft engine.

    摘要： Provided is a new control method that causes no time lag or hunting when a power conversion direction is reversed. The power conversion apparatus includes switching elements (S1 and S2) that alternately perform switching and are capable of reversing the power conversion direction without suspension, and an up/down counter register (RT) that has two different thresholds and selects counting up at a smaller threshold, counting down at a larger threshold, and holding of the value between the two thresholds. According to the value of the up/down counter register (RT), a gate pulse is generated to control the switching of the switching elements (S1 and S2).

    摘要： A stacked voltage source inverter having separate DC sources is described herein. This inverter is applicable to low or medium voltage, low to medium power applications such as photovoltaic utility interface systems, battery storage application such as peak shaving with renewables, motor drive applications and for electric vehicle drive systems. The stacked inverter consists of at least one phase wherein each phase has a plurality of low voltage full bridge inverters equipped with an independent DC source. This inverter develops a near sinusoidal approximation voltage waveform with fast switching and small low pass AC output filter. A system controller controls operating parameters for each inverter. The inverter may have either single-phase or multi-phase embodiments connected in either wye or delta configurations.
