    摘要: A solar panel is constructed by electrically connecting one or more banks of solar cells in series, wherein each cell in each bank is electrically connected in series. In some aspects the cells are a quarter of typical full size cells in the direction of current flow. A panel may comprise banks of differing cell counts. Bypass diodes are not used.

    摘要: Methods, apparatus and systems for controlling a photovoltaic panel while ensuring the power source operates safely include determining a temperature of the photovoltaic panel, determining a voltage provided from the photovoltaic panel, determining a parameter based on the voltage and the temperature and controlling a power converter based on the determined parameter. The power converter may be a pulse amplitude modulated current converter (PAMCC). The PAMCC may be controlled through tables of pulse durations based on the determined parameter. The voltage output may be controlled through a fast control loop and through a slower control loop, and the power demand from the solar panel may be controlled such that the output voltage does not vary from the expected value by more than a predetermined value.

    摘要: Methods, apparatus and systems for controlling a photovoltaic panel, to output three-phase power while ensuring the power source operates safely include determining a temperature of the photovoltaic panel, determining a voltage provided from the photovoltaic panel, determining a parameter based on the voltage and the temperature and controlling a DC to three-phase power converter based on the determined parameter. The three-phase power converter may be a pulse amplitude modulated current converter (PAMCC), configured to output first, second and third pulse amplitude modulated current pulse from three terminals controlled in timing and phase so that when respective outputs of multiple PAMCCs are connected, each phase of the plurality of PAMCCs is demodulated to produce a three-phase alternating current output. The PAMCC may be controlled through tables of pulse durations based on the determined parameter. The voltage output may be controlled through a fast control loop and through a slower control loop.

    摘要: Solar panels of certain technologies may experience a degradation of their efficiency as a result of exposure to sunlight, either prior to installation or during normal operation. A direct current to pulse amplitude modulated (“PAM”) current converter, denominated a “PAMCC”, is connected to the solar panel and to a source of alternating current. The PAMCC receives direct current from the solar panel and provides pulse amplitude modulated current at its output terminals at such times that the solar panel is capable to provide current, denominated “normal operation”. The PAMCC may be reconfigured to form a buck converter and a rectifier wherein the rectifier converts power received at the output (during normal operation) terminals to provide rectified, direct current to the buck converter. The buck converter provides direct current in the forward biased direction to the solar panel, thereby reconditioning the solar panel. Alternating current received at the output terminals of the PAMCC may be provided by an electric grid or by other means, such as other solar power converters.

    摘要: A direct current to pulse amplitude modulated (“PAM”) current converter, denominated a “PAMCC”, is connected to an individual source of direct current. Some embodiments provide a PAMCC for each direct current source in an array, for example multiple solar panels. The PAMCC receives direct current and provides pulse amplitude modulated current at its output. The pulses are produced at a high frequency relative to the signal modulated on a sequence of pulses. The signal modulated onto a sequence of pulses may represent portions of a lower frequency sine wave or other lower frequency waveform, including DC. When a PAMCC's output is connected in parallel with the outputs of similar PAMCCs an array of PAMCCs is formed, wherein the output pulses of the PAMCCs are out of phase with respect to each other. An array of PAMCCs constructed in accordance with the present invention form a distributed multiphase inverter whose combined output is the demodulated sum of the current pulse amplitude modulated by each PAMCC.

    摘要: A direct current to pulse amplitude modulated (“PAM”) current converter, denominated a “PAMCC”, is connected to an individual source of direct current. The PAMCC receives direct current and provides pulse amplitude modulated current at its three output terminals, wherein the current of each terminal is one hundred twenty degrees out of phase with the other two terminals. The pulses are produced at a high frequency relative to the signal modulated on a sequence of pulses. The signal modulated onto a sequence of pulses may represent portions of a lower frequency sine wave or other lower frequency waveform, including DC. When each phased output is connected in parallel with the outputs of similar PAMCCs an array of PAMCCs is formed, wherein each voltage phased output pulse is out of phase with respect to a corresponding current output pulse of the other PAMCCs. An array of PAMCCs constructed in accordance with the present invention form a distributed three-phase multiphase inverter whose combined output is the demodulated sum of the current pulse amplitude modulated by each PAMCC on each phase.
