Abstract
A constant current source includes an alternating current input, a pair of capacitors connected in parallel with a load output, a pair of diodes connected in parallel with the pair of capacitors, wherein a first lead of the alternating current input is connected between the pair of diodes and a second lead of the alternating current input is connected between the pair of capacitors, and wherein capacitances of the pair of capacitors are selected to produce a substantially constant current to the load output at a voltage lower than that of the alternating current input.
Claims1
An apparatus for providing constant current comprises:
- an alternating current input;
- a pair of capacitors connected in parallel with a load output;
- and
- a pair of diodes connected in parallel with the pair of capacitors, wherein a first lead of the alternating current input is connected between the pair of diodes and a second lead of the alternating current input is connected between the pair of capacitors, and wherein capacitances of the pair of capacitors are selected to produce a substantially constant current to the load output at a voltage lower than that of the alternating current input.
