摘要： A photovoltaic (PV) panel is described that can be used in a PV installation, in cooperation with a central control unit to provide a map of locations of individual PV panels. The map can be determined by the central control unit based on measurements of a characteristic made at the plurality of PV panels. The characteristic provides an indication of adjacent PV panels, allowing the map of locations of individual PV panels to be constructed.

摘要： PLL frequency synthesizers and their calibration techniques are described. The PLL frequency synthesizers are used to generate digital modulation of a carrier signal. A digital frequency divider in the feedback path of the loop has its division ratio controlled by a digital &Dgr;-&Sgr; modulator. The modulation of the carrier is achieved by applying a modulation signal to the input of the &Dgr;-&Sgr; modulator and to the input of the voltage-controlled oscillator of the PLL. The high frequency path and low frequency path of the modulation signal must be adjusted with respect to one another in order to obtain a good modulation. As the low frequency path can be accurately set, the calibration is performed only on the high frequency path. Digital calibration techniques for the high frequency path are described.

摘要： A One Bit Digital Quadrature Vector Modulator (DQVM) and a method of generating single sideband output signals are useful for a wide range of radio frequency, signal processing and wireless applications. The DQVM simplifies the necessary digital multiplication by using noise shaped one bit versions of both the baseband IB and QB signals to be modulated and the ILO and QLO modulating signals. The one bit DQVM enables a much faster digital implementation of the digital quadrature vector modulation function than can be achieved with conventional multi-bit digital techniques. In addition the single sideband upconversion of the DQVM achieves high suppression of the unwanted sideband by applying an offset to one of the low speed input samples. Digital vector modulators are an improvement over conventional analog vector modulators as they are not subject to the amplitude and phase matching problems inherent in analog vector modulators.

摘要： An inverter having extended lifetime DC-link capacitors for use with a DC power source such as a photovoltaic panel is described. The inverter uses a plurality of switchable capacitors to control the voltage across the capacitors. The expected lifetime of the capacitors can be extended by disconnecting unnecessary capacitors from a voltage. The capacitors may be periodically connected to a voltage in order to maintain an oxide dielectric layer of the capacitor.
