As the circuit operates, the three sets of diodes with their isolation capacitors, build up an increasing voltage on capacitor ?C1?. The voltage at point ?B? will also increase and be about twelve volts less than the voltage on capacitor ?C1?. Eventually, that voltage will rise high enough to cause a discharge through the tiny neon tube and that current pulse flows through the Gate connection ?G? of the thyristor, switching it on. Once switched on, the thyristor stays on until capacitor ?C1? has been discharged, after which, the thyristor switches off and the process starts all over again. The amount of power in these pulses is considerable and the thyristor gets quite warm when the circuit is running. The BT151-800R thyristor can handle as much as 800 volts and pass 7.5 amps of current continuously.
An important point to note is that the power available from this circuit increases with additional aerials. With two aerials connected, the power is doubled and with three aerials the power is tripled. That is, each additional aerial provides as much power as the first aerial did and there does not appear to be any limit to the number of aerials which can be connected.
The suggestion is that the aerial is suspended between the eaves of a house and a nearby tree, but I don?t know anybody who would be able to do that. The longer the aerial or the greater the number of aerials connected, the greater the charging power available. The aerial wire should be not less than 0.5 mm in diameter and it needs to be insulated from it?s supports ? plastic cord can be used for that.
The RF antenna connected to a circuit configured to convert the RF signals to Direct Current. The radio frequency signals received by the antenna are transmitted to two leads, one being rectified to produce positive voltage and the other rectified to produce negative voltage. The positive voltage lead is connected directly to a positive output line and the negative voltage lead is connected directly to a negative output line. The positive output line is connected to a pair of bus lines through a first pair of capacitors, while the negative output line is connected to the pair of bus lines by a second pair of capacitors. Placed between the first bus line...
