An IGBT/FET-based energy savings device, system and method wherein a predetermined amount of voltage below a nominal line voltage and/or below a nominal appliance voltage is saved, thereby conserving energy. Phase input connections are provided for inputting analog signals into the device and system. A magnetic flux concentrator senses the incoming analog signal and a volts zero crossing point detector determines the zero volts crossing point of the signal. The positive half cycle and negative half cycle of the signal are identified and routed to a digital signal processor for processing the signal. The signal is reduced by pulse width modulation and the reduced amount of energy is outputted, thereby yielding an energy savings for an end user.
