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.

Systems and methods for electrical power regulation and distribution in aircraft

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.
