Gate Opener (11/1/10) |
|
|
 |
This circuit provides
power to mechanical gates located opposite ends of a
looping branch tunnel. The gate is required to open and
close perhaps only 2 times each month. The gates are set
to open and then close again at ten minutes intervals.
The system is powered by a wind generator. But, the low
wind speed could mean that the voltage from the wind
generator might be slightly lower than the 14v needed to
keep the battery charged. |

Motorized Swing Gate |

The addition of a voltage doubler boost circuit to the three phase rectifier inside the generator solved the problem. The complete generator
circuit is shown below. The circuit provides a fixed 14v supply, current
limited to 100ma. |
