Abstract
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.
