摘要： Compact dynamic Phase Angle Regulators (CD-PARs) are provided. A Compact Dynamic Phase Angle Regulator (CD-PAR) is a stand-alone device that regulates phase angle through a single transformer. A CD-PAR has no external energy source, uses low-rating devices, and can be isolated from a fault in the grid. A CD-PAR may be implemented in a single-phase or in a three-phase configuration, but the operation of a CD-PAR cross-couples all three phases. A CD-PAR controls both the real and the reactive power flow between two AC sources having the same frequency by inserting a voltage with controllable magnitude and phase. A CD-PAR may be implemented in either a buck configuration or a boost configuration.

摘要： Isolated Dynamic-Current (“Dyna-C”) converters are converters that convert incoming 3-phase AC or DC power to a mix of DC and AC power via an isolation link. In various embodiments, the isolation link is a high-frequency isolation transformer. Isolated Dyna-C converters may provide a high-frequency galvanic isolation and are able to convert three-phase AC power to three-phase AC power, or three-phase AC power to DC and vice versa. The topology is minimal and the costs are low. Isolated Dyna-C converters provide fast current responses and keep the losses low by using a simplified two-stage conversion and providing a magnetizing current that is dynamically controllable and tailored to the load. An isolated Dyna-C converter may synthesize currents at its input or output ports with an arbitrary phase that is relative to the grid or load voltages, thereby enabling a full independent control over the active and reactive power at its ports.

摘要： Systems and methods for dynamic AC line voltage regulation are provided. A simple and cost-effective method for achieving AC line voltage regulation in AC systems including split-phase systems, of which the voltage for each voltage line may be regulated over a specified range, is provided. Buck and boost regulation is achieved for lowering or increasing the line voltage, respectively, with reference to the incoming grid voltage. Systems for dynamic AC line voltage regulation may comprise an AC/AC converter which uses fractionally rated switches and magnetics that handle only a fraction of the load current, resulting in lower costs. The use of an AC snubber further provides safe and robust switching of the main switching devices by eliminating failure prone switching sequences that are dependent on accurate assessment of voltage and/or current polarity for AC or bi-directional switches.
