A CAPACITIVE ELECTRIC CURRENT GENERATOR

摘要

A capacitive generator has a generator circuit (G) and a charge priming circuit (P) consisting of variable capacitors (1, 2, 101, 102) all coupled to a mechanical transmission which acts to vary the capacitance of the capacitors and to actuate an array of switches (K). A small residual charge on the priming circuit (P) can thus be amplified and conveyed to the generating circuit (G) where it is used to generate an alternating current between the variable capacitors (1, 2) of the generating circuit. The capacitance of the generating capacitors (1, 2) is varied in antiphase in response to the movement of the transmission. An electrical energy extraction device (8) in circuit with the generator capacitors (1, 2) extracts electrical energy from the circuit in reaction to the alternating current which can then be used to power or recharge a small portable device.
