This paper presents a new power electronic circuit that can be used for real and reactive power regulation in power systems. The circuit injects a sinusoidal current at variable phase and magnitude into the power system. The proposed high-frequency high-power resonant system is soft switched in most operating modes, less lossy, generates lower EMI, and has a faster response time than the currently available compensation schemes. The paper describes the concept of current injection for power quality control in power systems, verification using simulation studies, and proof-of-principle hardware implementation.
