Abstract:
1. A power generating engine mount for coupling an engine and a body of a vehicle, the engine undergoing vibration during operation, the power generating engine mount comprising: a first mounting stud configured for coupling to the engine; a permanent magnet coupled to the first mounting stud; a coil at least partially surrounding the permanent magnet such that, during operation, relative movement of the coil and permanent magnet converts mechanical energy from the vibration into electrical energy; a second mounting stud coupled to the coil and configured for coupling to the body; an energy storage device coupled to the coil configured to store the electrical energy and a power conditioner configured for coupling to the coil wherein the power conditioner comprises a first full-wave rectifier coupled to a first end of the coil, the first full-wave rectifier configured to receive a first sinusoidal waveform from the coil and to produce a first rectified waveform; a first low pass filter coupled to the first full-wave rectifier, the first low pass filter configured to receive the first rectified waveform and to produce a first filtered waveform; a first differential input buffer coupled to the first low pass filter, the first differential input buffer configured to receive the first filtered waveform and configured to produce a first signal forming at least a first portion of the electrical energy; a second full-wave rectifier coupled to a second end of the coil, the second full-wave rectifier configured to receive a second sinusoidal waveform from the coil and to produce a second rectified waveform; a second low pass filter coupled to the second full-wave rectifier, the second low pass filter configured to receive the second rectified waveform and to produce a second filtered waveform; a second differential input buffer coupled to the second low pass filter, the second differential input buffer configured to receive the second filtered waveform and configured to produce a second signal forming at least a second portion of the electrical energy; and a summer coupled to the first differential input buffer and the second differential input buffer, the summer configured to receive the first signal and the second signal and to produce the electrical energy as conditioned power.
