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： The value of an unknown voltage is measured by applying a time-varying current from a reference voltage source through a resistor to a capacitor thereby to increase the voltage across the capacitor as a function of time, measuring the time Tr required for the voltage across the capacitor to reach a selected reference voltage when current from the reference voltage source is applied to the capacitor, restoring the voltage across the capacitor to its initial state, applying a time varying current from an unknown voltage source through a resistor to the capacitor thereby to increase the voltage across the capacitor as a function of time, measuring the time Tb required for the voltage across the capacitor to reach a selected reference voltage when current from the unknown voltage source is applied to the capacitor and calculating the unknown voltage from the times Tr and Tb. The structure for implementing this process is controlled by a microprocessor and uses relatively low cost components compared to prior art dual slope voltage measuring structures.

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.
