摘要： A phase detector for a phase-locked loop includes a phase detector that is configured to become unstable, oscillate and drift rapidly in frequency in a predictable manner when a reference frequency signal is not available. When applied, for example, to a power converter connected to a power distribution grid, the predictable oscillatory and rapid frequency drift behavior when the phase detector is unstable allows very rapid and reliable detection of disconnection from the grid, referred to as islanding.

摘要： Gate control of power semiconductor devices using reduced gate drivers is disclosed. A circuit breaker may include a multitude of transistors, such as insulated gate bipolar transistors (IGBTs), connected in series with one another. Each transistor may be connected to a respective gate resistor. Diodes may be connected between various gate resistors. One or more resistor-capacitor (RC) snubber circuits may be provided in parallel with one or more of the transistors. Likewise, one or more metal-oxide varistors (MOVs) may be connected in parallel to one or more of the transistors. A gate driver (e.g., a single gate drive) may be connected to the one or more diodes and an emitter of at least one of transistors.

摘要： A rectifier is configured to convert a three-phase AC voltage to a 12-pulse DC voltage, drawing a 12-pulse AC current from a three-phase network. The rectifier may comprise a first interleaved phase-leg, a second interleaved phase-leg, and/or a third interleaved phase-leg. Respective interleaved phase-legs may comprise positive portions configured to conduct positive current from a transformer towards a load, and negative portions configured to conduct negative current from the load back to the transformer. The rectifier may be configured to sequentially cycle respective interleaved phase-legs into positive and/or negative 120 conducting states over a 360 degree cycle to output the 12-pulse DC voltage. For example, during a first 120 degree conducting state a positive portion of the first interleaved phase-leg may conduct positive current towards the load, while a negative portion of a different phase-leg may conduct negative current back to the transformer.
