摘要： 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.

摘要： A base unit is mechanically connected to the structure of a first electronic device. The base unit is round and includes conductive threads around the inside surface of an outer ring. The base unit may also include a center threaded post with conductive threads. The first electronic device is electrically connected to the base unit. A replaceable unit is sized such that it may screw into the base unit, the replaceable unit including matching threads which engage with the threads of the base unit. The threads of the replaceable unit are also electrically conductive, and are electrically connected to a second electronic device which is encapsulated within the replaceable unit. When the two pieces are screwed together the two electronic devices are thereby electrically connected. The first electronic device may be a solar panel. Another version of the invention does not include electrical connections.

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： A power converter circuit senses the output voltage (Vo) and controls the converter's duty cycle (d1) to provide a steady output current (Io) or input power (Pin) in each switching cycle (T). During an initial period (Tramp), the controller provides a possibly smaller target current (Iramp) to reduce the system stress while the output voltage rises to a suitable value (InitVtar).

摘要： To conserve power when regulating the output voltage (Vo) of a power converter, no adjustment is made to the converter's pulse width modulation times (Tp, Ts) even if the output voltage is off target (Vtar), provided that the output voltage does not change or is moving towards the target voltage. In some embodiments, the output voltage is not allowed to stay off target for more than a predetermined length of time. In some embodiments, the minimal adjustments are always large enough to overcome ringing (1004).

摘要： A method to compute an amount of energy taken from a battery coupled to a switching power converter is disclosed. The switching power converter charges a capacitor to a voltage and by the application of one or more control pulses to the switching power converter the voltage on the capacitor is maintained within a predetermined range having an upper voltage. The voltage on the capacitor is sampled and one or more control pulses are applied to the switching power converter to raise the voltage on the capacitor to the upper voltage. The amount of energy taken from the battery is computed based on measurement of a change in voltage on the capacitor over an elapsed time.
