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： 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.

摘要： Methods are disclosed for performing analog to digital signal conversion in shorter time and/or with less power consumption. A predictive guess is supplied as a digital first signal. The digital first signal is converted (D/A) to a counterpart, analog guess signal. A comparison is made between the analog guess signal and a received, analog input sample signal. The result of the comparison is used to improve on the initially supplied guess in a next cycle. Fewer cycles and less power is consumed if the initial guess is within a certain range of the actual magnitude of the analog input sample signal.

摘要： Methods and devices perform analog to digital signal conversion in shorter time and/or with less power consumption than that of a comparable analog to digital conversion that uses a conventional sequential approximation method based on a binary search. A predictive guess is supplied as a digital first signal. The digital first signal is converted (D/A) to a counterpart, analog guess signal. Fewer cycles and less power is consumed if the initial guess is within a certain range of the actual magnitude of the analog input sample signal. In one embodiment, a digital modeler is used to model a process underlying the analog input sample signal to thereby provide fairly good guesses.

摘要： The voltage applied to an integrated circuit is controlled by a temporal process monitor formed as part of the integrated circuit. The temporal process monitor includes a voltage controlled oscillator for producing a first output signal having a first period. A comparator compares the first period to one or more reference values. Should the first period be greater than a first selected reference value the comparator sends a signal to increase the voltage being supplied to the integrated circuit. Should the first period be less than a second selected reference value, the comparator sends a signal to decrease the voltage applied to the integrated circuit. In some embodiments a scaling circuit is provided for producing a second output signal having a second period different from (typically but not necessarily longer than) the first period. By placing the temporal process monitor on an integrated circuit chip, process variations and environmental factors which affect the performance of the integrated circuit can be automatically compensated so that the integrated circuit performs within specifications. Two or more temporal process monitors can be placed on a single integrated circuit chip or on different integrated circuit chips and the longest period produced by the temporal process monitors can be used to control the voltage supplied to all the sections of the integrated circuit chip associated with the temporal process monitors or to all the integrated circuit chips associated with the temporal process monitors.
