Abstract:
1. An energy savings device comprising: at least one phase input connection configured to input a predetermined amount of energy having at least one analog signal; at least one volts zero crossing point detector configured to determine at least one zero crossing point of said at least one analog signal; at least one half cycle identifier configured to identify at least one positive half cycle of said at least one analog signal and at least one negative half cycle of said at least one analog signal; at least one logic device configured to route said at least one positive half cycle of said at least one analog signal and said at least one negative half cycle of said at least one analog signal to at least one digital signal processor configured to process said at least one analog signal; at least one drive control configured to reduce said predetermined amount of energy by providing pulse width modulation to said at least one analog signal to yield a reduced amount of energy, wherein said at least one drive control is in electrical connection with said at least one digital signal processor; and at least one phase output connection configured to output said reduced amount of energy, wherein said at least one drive control comprises a positive half cycle control transistor configured to provide pulse width modulation to said at least one positive half cycle of said at least one analog signal, a negative half cycle control transistor configured to provide pulse width modulation to said at least one negative half cycle of said at least one analog signal, a first shunt control transistor and a second shunt control transistor configured as routing switches to clamp a back electromotive force.
