    摘要: A phase converter that converts single phase AC electric power to balanced three phase AC power. Two input terminals are connectable to a single phase AC power source, and connect directly to two output terminals of the converter. The phase converter has a storage capacitor, three active half bridge modules connected to the storage capacitor and a controller. Two modules connect to the input terminals and charge the storage capacitor. The other module connects to a third output terminal. The controller switches the module connected to the third output terminal and one of the other modules to generate and shape a second phase and a resultant third phase.

    摘要: A middle phase power-fetching type phase front/phase tail synchronized modulation circuit, comprising: a power supply unit, that is used to fetch power from the middle phase of an ordinary AC voltage waveform, and supplies it to a phase front/phase tail modulation unit as a normal operating voltage after rectification; and a phase front/phase tail modulation unit, it includes an MCU microcomputer, to control a driving circuit to turn-on, and control synchronously at least two bi-directional electronic power element, to generate a phase front/phase tail turn-on modulation signal. As such, while performing synchronous modulation from phase middle, phase front/phase tail can be retracted inward or expanded outward at the same time, so that phase front/phase tail turn-on output voltage average values complement each other, hereby achieving stable and modulated power supply.

    摘要: A system and method for controlling switching in an AC-AC converter is disclosed. A controller for the AC-AC converter determines a direction of current flow on supply lines that provide AC power to the AC-AC converter and determines a switching pattern for each of a plurality of line-side switches and each of a plurality of floating-neutral side switches in the AC-AC converter based on the determined direction of current flow on each of the supply lines. The controller causes the line-side switches and the floating-neutral side switches to operate in an ON or OFF condition according to the determined switching pattern, such that a controlled current flow is output from the AC-AC converter. The controller also implements a safe-switching routine when transitioning from a first switching pattern to a second switching pattern that prevents a non-zero current from being interrupted during the transitioning between the first and second switching patterns.

    摘要: A power conversion apparatus includes a power converter, an LC filter, and a controller. The power converter is disposed between an AC power source and a load. The LC filter is disposed between the AC power source and the power converter. The controller controls the power converter to perform power conversion control between the AC power source and the load. The controller includes a command generator, an oscillation component acquirer, a regulator, and an actuator. The command generator generates an input current command including a command of an input current of the power converter. The oscillation component acquirer acquires an oscillation component of a current flowing through a capacitor of the LC filter. The regulator regulates the input current command based on the oscillation component acquired by the oscillation component acquirer. The actuator controls the power converter based on the input current command regulated by the regulator.
