Abstract
An energy harvesting circuit is provided that consists of two parallel paths, each comprising a transformer, full wave rectifier, and capacitor. An ultra-low-power microcontroller operates a double-position double-throw switch, which switches the capacitors from charging from the input, to providing energy to the output.
Claims9
An AC-DC transducer for converting AC voltage to DC voltage, the AC-DC transducer having two parallel phases where each phase comprises:
- a. a step-down transformer [102] which is a miniature magnetic pulse-transformer connected to each phase of a split phased antenna, comprising a center-tapped primary and a plurality of secondaries;
- b. a full wave rectifier [103] connected to said step-down transformer [102] for converting the AC voltage to DC voltage;
- the AC-DC transducer further comprises:
- c. at least two capacitors [105], for storing the aggregated energy from said split-phased antenna, wherein, a first of said at least two capacitors is connected to a source for recharging while a second of said at least two capacitors is connected to a load providing smooth power supply thereto;
- d. a double-position double-throw switch [104] for eliminating flyback and switching said at least two capacitors alternatively between the load and the source;
- e. a means of operation [106] of said double-position double-throw switch;
- wherein said primary of said a step-down transformer [102] is connected to points on a split phased source [101] that are at largely opposite points of a voltage waveform impressed thereupon.
