摘要： A system configured to reduce the amplitude of reactive current present on a DC bus shared by multiple inverters is disclosed. The start of the switching period for the modulation routines of each inverter is synchronized, and a carrier phase angle is determined for a carrier signal within each of the inverters. The modulation routine of each inverter generates a reactive current on the shared DC bus. By controlling the carrier phase angle for each inverter, the reactive current of a first inverter may be generated at a phase angle that is offset from the phase angle of the reactive current generated by a second inverter. As a result, the reactive current from the first inverter cancels at least a portion of the reactive current from the second inverter, reducing the total reactive current present on the DC bus.

摘要： A thermostat compatible with single-HVAC- and dual-HVAC-transformer systems may include a first power return wire connector, a second power return wire connector, and a user-moveable mechanical element that physically blocks wire insertion into the first wire connector when in a first position and physically allows wire insertion into the first wire connector when in a second position. The thermostat may also include a switching circuit that may be in a first configuration when the mechanical element is in the first position, and in a second configuration when the mechanical element is in the second position. The first wire connector may be electrically coupled to the second wire connector in the first configuration, and first wire connector may be electrically isolated from the second wire connector in the second configuration to promote foolproofing against undesired isolation of the first and second wire connectors.

摘要： A thermostat is configured for automated compatibility with HVAC systems that are either single-HVAC-transformer systems or dual-HVAC-transformer systems. The compatibility is automated in that a manual jumper installation is not required for adaptation to either single-HVAC-transformer systems or dual-HVAC-transformer systems. The thermostat has a plurality of HVAC wire connectors including a first call relay wire connector, a first power return wire connector, a second call relay wire connector, and a second power return wire connector. The thermostat is configured such that if the first and second external wires have been inserted into the first and second power return wire connectors, respectively, then the first and second power return wire connectors are electrically isolated from each other. Otherwise, the first and second power return wire connectors are electrically shorted together.

摘要： A portable DC power manager (400) includes an internal power bus (410) and a plurality of device ports (1150, 1160, 1170, 1180, 1190, 1200) for connecting with external power and energy sources, external power loads and other external power managers. Each device port is isolated for the internal power bus by controllable switches (A, B, C, D). Power converters (440, 442, 510) may be disposed between device ports and the internal power bus to convert voltages and attenuate current amplitude. Energy management schema operating on the power manager sums available power and allocates the available power to connected power loads according to power priority settings. A hot-change-over circuit (1300) connects additional sources to the internal bus in response to a voltage drop on the internal power bus. A compact and lightweight package (1100) enables a portability.

One aspect of the invention provides a method for operating a power manager having a plurality of device ports for connecting with external power devices and a power bus for connecting with each device port. The method includes: disconnecting each device port from the power bus when no external power device is connected to the device port; accessing information from newly connected external power devices; determining if the newly connected external power devices can be connected to the power bus without power conversion; if not, determining if the newly connected external power devices can be connected to the power bus over an available power converter; and if so, configuring the available power converter for suitable power conversion.
