Abstract: A voltage or power conditioning and control device may be used in line with a source of AC line power (11, 12) and a reactive load (13) such as a single-phase induction motor. The device operates to absorb some of the power reflected by the AC load and generate a synthetic power wave to supplement and correct the applied power in level and phase. The device employs a pair of power capacitors (C1, C2) and a pair of electronic switch devices (Q1, Q2) each with a diode (D1, D2) in parallel. Gating or command signals (Figs. 2A, 2B, 2C) are generated based on the line voltage and timing, e.g., zero crossings. The phase or timing of the command signals is selected for a normal or no-boost mode, a voltage boost mode, or a voltage reduction mode. The capacitors are considered in series with the load, and improve the power factor to the load. A variation of this device may be used in conjunction with a solar array or other local power source.
