Abstract: A demand-based load balancing function may be provided by one or more drive controllers that takes advantage of the affinity laws to linearize the control of the variable of interest (e.g., flow, pressure, etc.). Each drive controller may be set up by the user simply inputting a few values into the drive controller. Based on the inputs, the drive controllers may interpolate control points using an assumed linear relationship between the variable to be controlled (e.g., pressure) and the current driven to the pump. Feedback data from the system may be used to continually update the drive controllers so as to potentially allow them to better balance power usage to each pump.

Abstract: In accordance with disclosed embodiments, a power conversion system and method are provided. The power conversion system comprises a main power source configured to deliver drive power to a load and an add-on power module. The add-on power module comprises an isolated DC/DC converter and a low voltage source coupled in series with a high voltage source. The add-on power module is coupled to the main power source and the load and configured to output boost power to the load. The power conversion system further comprises a controller coupled to the main power source and the add-on power module, wherein the controller is configured to: determine that the load requires power from the main power source, and if so, direct boost power from the add-on power module to the load; and direct drive power from the main power source to the load when boost power falls below a predetermined threshold.

Abstract: In accordance with presently disclosed embodiments, a hybrid power conversion system and method are provided. The hybrid power conversion system integrates multiple power sources. An isolated DC/DC converter manages power transfer between the power sources and the DC/DC converter and the power sources are connected such that a full power rating converter is not required. One of the power sources may comprise one or more battery strings, which may be selectively coupled to a DC/AC inverter. In one embodiment, the battery strings may be connected to a lead acid battery. Based on controller instructions, the isolated DC/DC converter replaces the power flow of the lead acid battery with the battery strings. In another embodiment, one or more battery strings may be selectively connected in series with a photovoltaic (PV) panel providing power to a load. When connected to the load, each of the battery strings may provide an incremental step up in power, boosting PV panel power.

Abstract: Present embodiments of the disclosure are directed to a zero-footprint charging station for use with vehicles having quick-charge batteries. The disclosed embodiments enable the “quick-charge” power conversion equipment to disappear entirely into a passenger station structure. The passenger station structure may include a structural component of a bus stop (or other vehicle station) that is designed to accommodate passengers waiting to board the bus (or other transportation vehicle). By housing the power conversion electronics within a larger structure that serves a purpose at the vehicle station, the system may enable larger amounts of power electronics to be incorporated into a relatively strong and stable structure conforming to a desired size for the area (e.g., bus stop).

Abstract: In accordance with presently disclosed embodiments, a multi-mode energy router (MMER) is provided. The MMER includes a functional block of power electronics under processor control. In addition, the MMER includes a plurality of switches that can be controlled to route power from specific sources or loads to the input or output of the functional block. The MMER enables a single functional block of power electronics to selectively provide bi-directional power conversion between AC and DC components and between DC and DC components.
