The present invention is a direct conversion programmable power controller that receives polyphase input power that has an input power frequency a polarity. The controller includes a primary chopper for each phase of electrical power. Each primary chopper is electrically connected in wye connection to a transformer. A secondary chopper demodulates and rectifies each phase of power. Each secondary chopper has an input connected electrically to the secondary terminals of the transformer and has an output connected to a load in series connection.
Direct Conversion Programmable Power Source Controller: Three-Phase Input With Programmable Single-Phase Output
The present invention is a system and method for a direct conversion programmable power source controller. The invention uses a sampling rate optimized for a transformer used to isolate or to step up or step down the power. The power is sampled at the source frequency and that sampling is phase-angle modulated according to a modulating signal at a frequency representing the sum of the frequencies of the power source and the desired output. After passing the power through the transformer, the invention then again chops that power to produce a multiplication of the power sinusoid with the modulation sinusoid. The output is filtered to integrate the waveform and fed to a load in delta. Between any two terminals of the delta connection, the output voltage presents as a well-formed sinusoid of controlled amplitude and frequency.
Multiple Mode Universal Power Source Utilizing A Rotating Machine
A programmable motor controller for receiving three-phase input power at an input power frequency and having a polarity is presented. The controller includes a primary chopper for reversing each phase of electrical power according to a reference frequency. Each primary chopper has a power input, a signal input, and an output. The power input is electrically connected in wye connection to each phase of power. A transformer for each phase of power has primary and secondary terminals and is connected electrically by its primary terminals to the output of the primary chopper. A secondary chopper for each phase of power is configured to reverse each phase or electrical power according to the reference frequency and phase shifted according to a second reference signal. The secondary chopper has an input connected electrically to the secondary terminals of the transformer in an output connected to a winding of a motor.
A direct conversion programmable power controller receiving polyphase input power at an input power frequency and with a polarity is provided. The controller includes a primary chopper for reversing each phase of electrical power according to a reference frequency that is substantially higher than frequency of the electrical power. Each primary chopper has a power input, a signal input, and an output. The power input is electrically connected in wye-connection to each phase of power. A transformer for each phase of power has primary and secondary terminals and is electrically connected by its primary terminals to the output of the primary chopper. A secondary chopper for each phase of power has an input connected electrically to the secondary terminals of the transformer. The secondary chopper is configured to reverse each phase of electrical power according to the reference frequency and to shift phases of electrical power according to a reference signal.

International Classification:
B60L 1/00 F23Q 7/24 H05B 43/02
US Classification:
361248, 307 91
Abstract:
A squib firing device is constructed to test and fire a squib load being applied to the squib firing device. A power supply of the squib firing device conditionally stores and discharges a squib firing power, which is a function of an analog OR of a first voltage from an external power source and a second voltage from a battery source of the squib firing device. When the squib firing power is being stored by the power supply, the squib firing device establishes a flow of a squib testing current through the applied squib load to thereby detect a resistance of squib load. When the squib firing power is being discharged by the power supply, the squib firing device establishes and regulates a flow of a squib firing current through the applied squib load to thereby fire squib load.

Abstract:
A power supply system operable to supply power and/or data to aircraft passenger seats that eliminates the need to extend individual cables to each seat and eliminates the need to rewire the passenger cabin when the seats are moved. The system includes a first connector housing secured to a first seat leg and a second connector housing secured to at least one of the first seat leg and the second leg. A first connector of a seat electronic subsystem is mounted to the first housing. A second connector of the seat electronic subsystem is mounted to the second housing. A conductor is operable to mate with at least one of the first connector and the second connector for conducting at least one of data and electricity to or from the seat.

US Classification:
363163, 363164, 329325, 329321
Abstract:
The present invention comprises systems and methods for electrical power regulation and distribution. In an embodiment, a system includes a modulator coupled to the source that receives an unregulated output waveform and is operable to produce a first composite waveform, and a mixing unit that is operable to generate a second composite waveform by introducing a frequency modulated component into the first composite waveform. A demodulator is coupled to the mixing unit that demodulates the second composite waveform to generate a third composite waveform. A filter network is coupled to the demodulator that is configured to select a desired spectral portion of the third composite waveform.
