    Abstract: High performance gate drives and methods for driving semiconductor switching elements, such as insulated gate bipolar transistors (IGBTs), are provided. The gate drive can control the voltage applied to the gate of the IGBT to one or more intermediate voltages near the threshold voltage of the IGBT to control dv/dt of the collector-emitter voltage during and the di/dt of the collector current turn off. For instance, a voltage level between the turn on voltage and the turn off voltage can be applied for a first time period to control dv/dt of the collector-emitter voltage and di/dt of the collector current during turn off. Another voltage level between the turn on voltage and the turn off voltage can be applied for a second time period during reverse recovery of a freewheeling diode coupled in parallel with the IGBT.

    Abstract: The present subject matter is directed to a system and method for controlling an electrical component, e.g. a power bridge, of a wind turbine using contingency communications. In one embodiment, the method includes receiving, by the electrical component, a standard set of commands for a first time frame. A next step includes receiving, by the electrical component, one or more contingency sets of commands for time frames beyond the first time frame. The method also includes determining if the standard set of commands is received within a start window of the first time frame. A further step includes implementing, by the electrical component, the standard set of commands during the first time frame if the standard set of commands is received within the start window. The method also includes implementing, by the electrical component, one of the contingency sets of commands received during a previous time frame if the standard set of commands is not received within the start window.

    Abstract: Magnetic components that can be used to provide normal mode and common mode inductance in a power system, such as a wind-driven doubly fed induction generator system, are provided. The magnetic components can include a structure that combines both normal mode inductors and common mode inductors on a common core. In particular, the magnetic components can include specific winding and core arrangements which couple a common mode inductor and a normal mode inductor onto a single core with at least three legs. The structure of the magnetic components can be smaller in size, can have lower weight, and can have a lower cost than typical solutions to providing common mode and normal mode inductance in a power system.

    Abstract: The present subject matter is directed to apparatus and methods for producing a variable frequency output waveform from a power converter for use in a power generation system, such as a wind turbine power generation system. A voltage divider is employed to provide plural voltage levels to which a multi-level bridge circuit employing selectively activated switches in pairs of switches is coupled. The switches are operated in such a fashion as to produce a generally sinusoidal waveform that may be easily filtered by low cost filters due to the plural voltage levels to produce a generally smooth sine wave from the converter. Such converters may be used in various environments including in pairs in multi-phase power converters.
