Abstract
A power description is given of the operation and design of a power-line conditioner (PLC) utilizing the principles of a resonant converter. The PLC uses an L-C circuit which resonates at a high frequency. The PLC is connected in parallel with a load, and it injects high-frequency resonant current pulses into the supply lines at regular sampling intervals so that the resultant line current closely approximates a sine wave in phase with the supply voltage. Computer simulation results of the PLC for several typical loads indicate a high level of performance.<>
