Method and apparatus for controlling the voltage of signals powering low voltage lighting systems

A method of controlling the voltage of a power signal for a plurality of electrical loads comprising:

• receiving an AC power signal from a secondary portion of a power transformer, wherein the AC power signal is at a voltage greater than a specified level corresponding to the plurality of electrical loads;
• adjusting the voltage of the AC power signal to a voltage level such that the voltage supplied to the plurality of electrical loads is at the specified level;
• and
• maintaining the voltage of the AC power signal at the specified level regardless of a change in a voltage drop experienced by the AC power signal.

A voltage feedback for a power control system for outdoor lighting systems comprising:

• a switch inputting an input AC power signal and for providing an AC output power signal to a plurality of lamp loads;
• a controller coupled to the switch and controlling the operation of the switch;
• and
• a logic rectifier circuit coupled to the controller wherein the logic rectifier circuit inputs the AC output power signal and a return AC power signal from the plurality of lamp loads, wherein the logic rectifier circuit provides a rectified voltage feedback signal for the controller which is used to adjust the operation of the switch.

A current feedback for a power control system for outdoor lighting systems comprising:

• a switch inputting an input AC power signal and for providing an AC output power signal to a plurality of lamp loads;
• a controller coupled to the switch for controlling the operation of the switch;
• and
• a logic rectifier circuit coupled to the controller wherein the logic rectifier circuit inputs the AC output power signal across a current sense resistor, wherein the logic rectifier circuit provides a rectified current feedback signal for the controller which is used to adjust the operation of the switch.
