摘要： A harmonic blocking converter system for converting power between an AC source and a DC source includes a harmonic blocking transformer and a converter which generates undesirable harmonic currents including fifth and seventh harmonic components. The harmonic blocking transformer includes a polyphase main transformer and a harmonic blocker coupled with wye and delta secondary windings of the main transformer, so as to substantially block passage of the fifth and seventh harmonic currents to the AC source. A waveform enhancer may couple the harmonic blocking transformer with the converter. The converter may be constructed for 2-level operation, or, with the addition of auxiliary diodes, for 3-level operation. Such a harmonic blocking transformer and a method of blocking undesirable harmonic currents are also provided.

摘要： A system for determining an operational state of an atmospheric pressure plasma. The system has a transformer for coupling power into the atmospheric pressure plasma, a current sampling circuit configured to sample at least one current pulse flowing through a primary winding of the transformer, and a programmed microprocessor configured to determine, from a waveform of the current pulse, the operational state of the atmospheric pressure plasma. The operational state is one of: a no plasma state, a plasma origination state indicative of an ignited arc expanding into a plasma by gas flow thereinto, and a plasma maintenance state indicative of the plasma being expanded.

摘要： Methods and apparatus for flux cancellation includes first and second inductors. A system cam include first and second inductors and a layer of magnetic material disposed between the first inductor and the second inductor. In embodiments, when the inductors are driven with a respective oscillating current, at least a portion of magnetic flux generated by the first inductor is substantially canceled by at least a portion of magnetic flux generated by the second inductor in the layer of magnetic material.

摘要： The disclosure provides a communication circuit including an amplification circuit, a replicator circuit, and a correction circuit. Specifically, the amplification circuit generates an amplified signal. The replicator circuit emulates the amplification circuit and generates a replicated signal that approximates the amplified signal. The replicated signal is used by the correction circuit to generate control signals for controlling the amplification circuit.

摘要： A transformer (900) comprising a primary-side auxiliary winding (976, wherein in use the primary-side auxiliary winding (976) is configured such that a first electric potential distribution is induced in the primary-side auxiliary winding (976); and a secondary-side auxiliary winding (982) configured such that a second electric potential distribution is induced in the secondary-side auxiliary winding (982). The primary-side auxiliary winding (976) is physically located between (a) a main pair of windings; and (b) the second-side auxiliary winding (982). A first portion of the secondary-side auxiliary winding (982) is positioned adjacent to a shield-portion of the primary-side auxiliary winding (976) such that the first electric potential distribution matches the second electric potential distribution: (1) along the respective lengths of the first portion of the secondary-side auxiliary winding (982) and the shield-portion of the primary-side auxiliary winding (975); and (2) over a frequency range that is greater than a particular threshold frequency.
