| 20110115299 | High Voltage Array Converter - 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 output. 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. The array is configured as a series of stages, wherein the power sources within each stage are in parallel. The series of stages provides for a high voltage AC or DC output. In some embodiments a weak power source is compensated for by adjusting the voltage or the current of the weak power source. | 05-19-2011 |
| 20110057516 | THREE PHASE POWER GENERATION FROM A PLURALITY OF DIRECT CURRENT SOURCES - 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. | 03-10-2011 |

| 20110028008 | PROGRAMMABLE STRUCTURE FOR PASSING PARAMETERS TO A CONTROLLER - An enclosure includes a base unit and an insertable unit wherein the base unit has an opening corresponding to the insertable unit. A single structure is formed when the insertable unit is inserted into the base. The base is electrically connected to a first electronic device, such as a solar panel. The insertable unit includes a second electronic device. The base and the insertable unit have connectors that make electrical connections when the insertable unit is inserted into the base unit. The base unit further includes electrical connectors connected to a memory device wherein the electrical connections correspond to matching connections in the insertable unit. Upon assembly the second electronic device reads data prepositioned in the memory device, thereby passing data to the second electronic device. The data may be parametric, characteristic, flag, or a serial number, for example. | 02-03-2011 |
| 20100332167 | METHOD FOR DETERMINING THE OPERATING CONDITION OF A PHOTOVOLTAIC PANEL - Due to their exposure to extreme environments, it is expected that parts or all of a solar power system will experience degradation in performance. The degradation may be due to temporary environmental factors, such as cloud cover; damage or localized soiling; a general dirty condition; or ageing of the components. A method is disclosed wherein a remote system may detect degraded performance and determine the cause, thereby enabling a decision as to the appropriate corrective action to be taken, if any. | 12-30-2010 |
| 20100301817 | METHOD FOR CONTROLLING ELECTRICAL POWER - Power output of a power generation system is controlled by measuring the output voltage of the system, dividing the measured voltage value into a target power value, then controlling the current provided by the generation system to the calculated value. In some embodiments the power generation system is connected to a grid. | 12-02-2010 |
