摘要： Cross-channel interference can be a problem in multi-channel switched power systems. A multi-channel switched power converter is provided a reference count generator that generates a reference count signal that is commonly distributed to multiple, pulse width modulating (PWM) channels of the converter. The common reference count signal counts through a sequence of successive timing values. Events in each channel are scheduled relative to the common reference count. Examples of such events include the amplification or de-application of a driving voltage pulse to an inductive means of the channel and the taking of voltage and current measurement samples. Cross channel interference is avoided or minimized by scheduling or re-scheduling events in each active channel so that they do not occur simultaneously in potentially-interfering channels, for example the taking of a current measurement sample in one channel and the turning on of an inductance-driving voltage pulse is a second channel.

摘要： The clipper contained in the standard cellular transceiver used in cellular telephone networks is effectively prevented from having any effect on a signal by reducing the signal amplitude so that the signal which passes through the clipper does not activate the clipper. The signal from the clipper is then re-amplified prior to being passed to the modulator for transmission over the airwaves. The signal power is further increased by adding a selected de-emphasis circuit to the system prior to the transmitter, the de-emphasis circuit causing the frequency components of the signal to decline in amplitude as a function of frequency by a selected amount, 6 dB per octave in one embodiment.

摘要： A system comprising an array of solar panels, each panel including an electronic control module, wherein the panels are all connected in electrical series with each other and to a switch and to a string inverter, may be signaled to power down each panel to a safe output at its output terminals. The method includes sensing output wave forms of a module to be the result of its own DC-DC converter output or to be at variance with the expected output. Output wave forms at variance indicate that the control module is connected in electrical series with the input capacitance of the string inverter. If the output is as expected, the control module is deemed to not be connected to the capacitance of the string inverter as a result of the electrical series switch being open. The module then immediately drives its output to a safe level.

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 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 the 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.
