Methods and systems for synchronizing an electric grid having unbalanced voltages are provided. Voltage vectors may be synchronized in a phase-locked-loop configured to maintain synchronous operation of the grid even when the voltages are unbalanced. For e...

Embodiments of the present invention provide novel techniques for using a switched converter to provide for three-phase alternating current (AC) rectification, regenerative braking, and direct current (DC) voltage boosting. In particular, one of the three ...

Current source converter (CSC) based wind energy power conversion systems (WECS) and methods are presented in which a unified DC link current control scheme is employed to facilitate grid fault ride-through conditions, with a multiple-mode converter contro...

Current source converter (CSC) based motor drives and control techniques are presented in which DC link current is regulated to a level set by the output inverter during dynamic braking operation by pulse width modulation of a braking resistance connection...

A control system for an energy-related system including at least a first energy consumer and a first energy producer, and related method, are disclosed. The control system includes a first agent in communication with the first energy consumer for the purpo...

In one embodiment, the components within each respective unit of the MCC are connected powered by a connector assembly that is directly engaged to secondary power and network data conductors disposed of within the enclosure. The connector assembly, if so d...

A network is configured to apply power and data signals to networked devices for operation of the devices. A backup power supply module is coupled to the source of network power and to a secondary power source. The secondary power source may have an adjust...

A technique is provided for applying secondary or backup power (22) to a networked device (18) in the event of a loss or malfunction of network power. In a control and monitoring network (10). Various devices may receive both power and data signals from a ...
