    Abstract: In distributed green-energy architectures, where a customer location has energy storage as well as local generation, the present application provides techniques which advantageously prevent the battery from being charged from the grid. This is preferably implemented by using voltage-level signaling to limit power transfer from grid to battery, thereby 1) allowing transfer from PV to battery, and 2) preventing round-trip transfer of net energy from grid to battery to grid. This is particularly advantageous where net energy metering is allowed, or where any analogous form of preferential pricing is given to green energy (or to solar energy specifically).

    Abstract: An active anti-islanding architecture where a power converter injects a current component at a harmonic of the fundamental power frequency is injected with a phase sequence opposite to that which normally be present with that harmonic. (For example, a 5th harmonic frequency can be used with a positive phase sequence, or a 7th harmonic frequency with a negative phase sequence.) The injected current component can have a thousandth or less of the power transferred by the converter, since the distinctive phase sequence of the injected signal facilitates recognition of a corresponding term in the observed voltage.

    Abstract: The present application discloses new approaches to providing passive-off protection for a B-TRAN-like device. Even if the control circuitry is inactive, AC coupling uses transient voltage on the external terminals to prevent forward biasing an emitter junction. Preferably the same switches which implement diode-mode and pre-turnoff operation are used as part of the passive-off circuit operation.

    Abstract: Methods and systems for managing link voltages in a power converter, where single phase, three phase or universal systems can be used. Common mode management refers to shifting of voltages in a particular direction to perform transition between input and output ports, in addition to maintaining soft switching property. Voltages in power converters can be freely increasing and decreasing, and thus damage to the circuit can be caused if these voltages change are not controlled.

    Abstract: Operating a bi-directional double-base bipolar junction transistor (B-TRAN). One example is a method comprising: conducting a first load current from an upper terminal of the power module to an upper collector-emitter of the transistor, through the transistor, and from a lower collector-emitter to a lower terminal of the power module; and then responsive assertion of a first interrupt signal, interrupting the first load current from the lower collector-emitter to the lower terminal by opening a lower-main FET and thereby commutating a first shutoff current through a lower base of the transistor to the lower terminal; and blocking current from the upper terminal to the lower terminal by the transistor.

    Abstract: Power converters, and microgrids driven by such a power converter, in which the converter is controlled by a proportional controller which operates directly on AC waveforms, preferably without conversion to a DC type signal; preferably with use of voltage compensation to remove inherent error of proportional controller; and preferably with use of individual phase RMS voltages in the voltage compensation, to allow for normal operation under any load condition. Undervoltage of one or two phases is automatically compensated by adjusting the voltage of all phases, to retain balance. Line-starting of a motor load is automatically detected, and frequency droop is driven, apart from the other control relations in the system, to complete the line-starting operation as quickly as possible.

    Abstract: Methods and systems for active charge control diodes with improved reverse recovery characteristics. An extra control terminal is added on the side of a diode nearest to its p-n junction. The control terminal connects to a control region which extends from the drift region to the cathode surface and which is most preferably separated from the cathode region by an insulated trench. During turn-off, the control terminal is most preferably driven negative relative to the cathode just before reversing the polarity of the applied external voltage.
