| Title: |
Techniques for Controlling Remote Lamp Loads |
| Abstract: |
For energizing remote lamp loads subjected to indeterminate transmission
losses, a current regulating power supply is described which delivers a
regulated current to the load using for example, a full wave rectifier
supplying an unfiltered pulsating voltage to a switching regulator
controlled by a feedback loop incorporating a current sensing resistor and
pulse width modulator. The supply has a substantially unity power factor,
a self-quenching characteristic in the presence of circuit interruptions,
and can deliver regulated current to a variety of lamp types.
