Inverter communications using output signal

Chapman, Patrick L.

Title: Inverter communications using output signal

Abstract

Technologies for communicating information from an inverter configured for the conversion of direct current (DC) power generated from an alternative source to alternating current (AC) power are disclosed. The technologies include determining information to be transmitted from the inverter over a power line cable connected to the inverter and controlling the operation of an output converter of the inverter as a function of the information to be transmitted to cause the output converter to generate an output waveform having the information modulated thereon.

Inverter communications using output signal

Patent Chapman, Patrick L.

Technologies for communicating information from an inverter configured for the conversion of direct current (DC) power generated from an alternative source to alternating current (AC) power are disclosed. The technologies include determining information to be transmitted from the inverter over a power line cable connected to the inverter and controlling the operation of an output converter of the inverter as a function of the information to be transmitted to cause the output converter to generate an output waveform having the information modulated thereon.

Electrical system for pulse-width modulated control of a power inverter using phase-shifted carrier signals and related operating methods

Patent Welchko, Brian A [Torrance, CA]

Systems and methods are provided for pulse-width modulated control of power inverter using phase-shifted carrier signals. An electrical system comprises an energy source and a motor. The motor has a first set of windings and a second set of windings, which are electrically isolated from each other. An inverter module is coupled between the energy source and the motor and comprises a first set of phase legs coupled to the first set of windings and a second set of phase legs coupled to the second set of windings. A controller is coupled to the inverter module and is configured tomore »« less

Communication device, spread-spectrum receiver, and related method using normalized matched filter for improving signal-to-noise ratio in harsh environments

Patent Moradi, Hussein; Driggs, Jonathan D.; Majid, Arslan J.; ...

A communication device, a method of operating a communication device, and a spread-spectrum receiver are disclosed. The method includes receiving an incoming RF signal, demodulating the incoming RF signal to generate a baseband signal, filtering the baseband signal with a normalized matched filter having filter characteristics matched to a pulse-shaping filter of the transmitter that generated the incoming RF signal, and extracting a received signal from a normalized output generated by the normalized matched filter. As a result, interferences and noise from harsh environments may be suppressed.

Method and apparatus for improving resolution in spectrometers processing output steps from non-ideal signal sources

Patent Warburton, William K.; Momayezi, Michael

A method and apparatus for processing step-like output signals (primary signals) generated by non-ideal, for example, nominally single-pole ("N-1P ") devices. An exemplary method includes creating a set of secondary signals by directing the primary signal along a plurality of signal paths to a signal summation point, summing the secondary signals reaching the signal summation point after propagating along the signal paths to provide a summed signal, performing a filtering or delaying operation in at least one of said signal paths so that the secondary signals reaching said summing point have a defined time correlation with respect to one another,more »« less

Delayed boost of driver output signals

Patent Luckett, Edward James; Poirier, Christopher Allan

According to examples, an apparatus may include a field effect transistor (FET), a driver to receive an input signal and to output a driver output signal, and a gate to receive the input signal. The apparatus may also include a delay element to receive the driver output signal and to output a delayed signal to the gate after a delay from receipt of the driver output signal, in which the gate is to output a gate output signal to the FET in response to receipt of the input signal and the delayed signal, and in which receipt of the gatemore »« less
