Universal DC Sink to Source
Converter |
| As illustrated below,
many control systems use an open collector transistor to turn something on.
Perhaps it is a LED light, a relay or a small motor. However there are other
systems which require a common ground connection instead of a common V+ supply
connection. |
|
|
The circuit
below converts the "sink to ground" current path to a "supply source" power connection.
With the components shown, the circuit will operate over a wind 3v to 28v range with a
current up to 1 Amp. |
