摘要： Audio Frequency Load Control (AFLC) signal processing electronics added to a power factor correction (PFC) unit allowing the AFLC system to operate without the need of large and heavy passive bypass or blocking filters at the PFC installations. The AFLC signal processing electronics a first group of additional electronics tuned to the AFLC frequency for detecting the AFLC carrier signal; and a second group of additional electronics for driving an AFLC impedance switch that is connected in parallel with an AFLC impedance. The AFLC impedance is connected in series with the PFC capacitors, and is sufficiently large to offer significant impedance in series with the PFC capacitors that allows the AFLC signal to bypass the PFC unit.

摘要： Legacy automatic variable capacitor KVAR compensation systems typically use either electromechanical devices such as relays or contactors of various forms and types to switch the selected capacitors in and out of the electrical system under some form of electronic control. These systems are slow and discontinuous in their ability to closely regulate the exact value of compensatory capacitance needed to compensate the variable and rapidly changing reactive power KVAR in the electrical power transmission and distribution networks. The present invention provides a fast response active KVAR compensator based on a variable transimpedance topology.
