Patent ID: 8085010

Claim:
An TRIAC/SCR-based energy savings device comprising: at least one phase input connection for inputting a predetermined amount of incoming energy having at least one analog signal into said energy savings device, wherein said at least one analog signal is an AC signal; at least one sensing means connected to said at least one phase input connection for sensing said predetermined amount of incoming energy entered into said energy savings device; at least one volts zero crossing point detector in electrical connection with said at least one phase input connection for determining at least one zero volts crossing point of said at least one analog signal; at least one digital signal processor in electrical connection with said at least one volts zero crossing point detector for processing said at least one analog signal; at least one voltage reducing means having at least one drive control wherein said at least one voltage reducing means is in electrical connection with said at least one digital signal processor for reducing said predetermined amount of incoming energy by providing pulse width modulation to the at least one analog signal to yield a reduced amount of energy; and at least one phase output connection in electrical connection with said at least one voltage reducing means for outputting said reduced amount of energy out of said energy savings device; wherein said digital signal processor is configured to determine a firing angle of said at least one analog signal that will provide a predetermined root-mean-square voltage; and wherein said at least one drive control is configured to reduce said predetermined amount of incoming energy to said predetermined root-mean-square voltage using said firing angle.
