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.

Abstract: A system and method are provided for reducing the energy consumed by a pump jack electric motor by reducing the supply voltage to the motor when the motor would be generating energy in open loop mode. By substantially eliminating the energy generation mode, the braking action of the utility grid in limiting the acceleration of the motor and system that would otherwise occur is substantially removed. The motor and system will speed up, allowing the natural kinetic energy of the cyclic motion to perform part of the pumping action. In particular, when the energy consumption for the electric motor connected with the device having a rotating or reciprocating mass goes to zero, the line voltage to the motor is switched off, causing the frequency of the voltage across the motor terminals to increase. When the period of the voltage across the motor terminals returns to substantially the same as the period of the line voltage, the line voltage is switched on or reapplied to the motor.

Abstract: A system and method are provided for saving energy for an electric motor having periodic load variations by reducing the supply voltage to the motor during an open loop mode. The motor and system will speed up, allowing the natural kinetic energy of the cyclic motion to perform part of the pumping action. A closed loop controller computes information from the observed phase angle between the voltage and current supplied to the motor. By reducing the supply voltage to the motor, the observed phase angle may be reduced to a target phase angle value. By allowing some current flow, primarily of a reactive nature, an observable feedback parameter may be used in the closed loop control system as an indication of the load condition, to which the closed loop motor controller may react, supplying power when needed, such as in the energy consumption mode.

Abstract: A system and method are provided for increasing and maintaining voltage. A transformer's secondary windings are connected between the hot input line and the hot output line, and are not switched. The secondary windings may be in series for 220/230 Vrms, and in parallel for 120/127 Vrms. Alternatively, the transformer may be a single voltage type specifically for 230 V, 120 V, or any other voltage range. A microprocessor measures incoming voltage and controls an electronic switch on the primary windings side of the transformer to short circuit the primary windings when the transformer is not needed. When voltage boost is needed, the switch may be controlled to connect the primary windings to neutral. When the primary windings are switched to neutral, the secondary voltage adds to the incoming AC line voltage. There may be multiple taps on the primary windings selected by the microprocessor for providing differing boost levels at differing input voltage levels.

Abstract: A system and method are provided for managing electrical power usage. During a predetermined time period, such as during blackout conditions, a digital signal processor (DSP) controls an IGBT/FET-based device to supply an allocated amount of power. When the consumed amount of power exceeds the allocated amount, the DSP shuts off the power. Alternatively, the system provides a signal to reduce the consumed power. If sufficient load has not been reduced after a predetermined amount of time, the power is shut off. Further alternatively or in addition, the DSP may shut off power to predetermined electrical outlets, while providing power to other electrical outlets, to reduce the power usage to the predetermined amount. During other time periods, the DSP controls the IGBT/FET device to provide a predetermined voltage that is less than the AC incoming line voltage.
