Abstract: In a multiphase electrical power construction and assignment, a processor: determines a phase and voltage configuration for bi-directional power device pairs; determines a given bi-directional power device pair is to be coupled to a given phase connection based on the configuration; determines whether the given bi-directional power devices in the given bi-directional power device pair are to be coupled to each other; confirms that the given bi-directional power device pair is not coupled to any of the plurality of phase connections; couples the given bi-directional power device pair to the given phase connections, where power signals of the given bi-directional power device pair are synchronized with a power signal of the given phase connection; and in response to determining that the given bi-directional power devices are to be coupled to each other, couples each of the bi-directional power devices to a short bus.

Abstract: The invention provides a bidirectional converter that operates under an AC generation mode or a charge mode. The bidirectional converter may be a single component or circuit, which may include a DC-DC conversion stage using a unique “Smith 2 Stage conversion” technique and a DC-AC conversion stage or AC-DC conversion stage using a switchable filter depending on the mode. During the charge mode, the converter may be able to control the voltage and current of the DC output using a software algorithm, to match the battery being charged, or the DC receiver. This may enable the converter to control the nature of the DC output so it can be adapted to any energy storage technology. The controllable output voltage and synchronizable frequency may allow the converter to be used in series combinations to achieve a variety of high voltage outputs from simpler building blocks.
