TL;DR: In this paper, a selective voltage harmonic compensation strategy for stand-alone inverters is proposed to compensate the voltage harmonic distortion and produce sinusoidal voltage by adding virtual impedances to the fundamental voltage control.
Abstract: This paper proposes a selective voltage harmonic compensation strategy for stand-alone inverters The use of LC output filters makes it possible to reduce switching harmonics at the output terminals of the inverter; however, it also produces voltage distortion when feeding nonlinear loads due to the harmonic voltage drop across the filter inductances To compensate the voltage harmonic distortion and produce sinusoidal voltage, it is proposed to add virtual impedances to the fundamental voltage control The whole process and considerations for the impedance design are described and a stability analysis of the system is presented Finally, simulations and experimental results are shown to confirm the good performance of the proposed strategy under both steady state and load steps

Abstract: A method for constructing a direct-current to direct current (DC-DC) converter from an input voltage to an output voltage. The DC-DC converter has multiple capacitors and multiple switches connectible the capacitors. A target voltage ratio is obtained based on the input voltage and the output voltage. The target voltage is expressed as a radix number. The radix number is spawned into a code of the target voltage ratio. The code is translated into a switched-capacitor converter (SCC) configuration including the switches and the capacitors. The code may be an extended binary representation code or a Generic Fractional Numbers code. The switched-capacitor converter (SCC) configuration is preferably modified to obtain charge balance.

28 Sep 2001TL;DR: In this paper, an adaptive impedance matching scheme is proposed to match the impedance of a bus and is controlled according to control bits supplied by the control circuit, which are updated according to a signal indicating the state of a queue maintaining transactions for the bus.
Abstract: An adaptive impedance matching arrangement has an adaptive impedance circuit and a control circuit. The adaptive impedance circuit matches the impedance of a bus and is controlled according to control bits supplied by the control circuit. The control bits are updated according to a signal indicating the state of a queue maintaining transactions for the bus.
