Abstract:
An electrical circuit for transferring energy from an energy source having a source voltage, to a capacitive store, comprising:a starter switching means for closing to electrically communicate an initial current from the energy source, with a capacitive means; a rectifier means electrically communicating with the capacitive means, for charging the capacitive store with energy from the initial current; the capacitive means having a variable capacitive voltage opposing the source voltage, for reducing the initial current to a null magnitude, and also for generating a reverse current when the capacitive voltage exceeds the source voltage; the starter switching means also for opening when the initial current decreases to a null magnitude; the capacitive means electrically communicating with a trap switching means; the trap switching means being for closing when the reverse current is generated, for electrically communicating the reverse current with the rectifier means when closed, and for opening when the reverse current has a null magnitude; and the rectifier means also for charging the capacitive store with energy from the reverse current, whereby the capacitive store is being charged by both the initial current and the reverse current.
