This paper presents part of the investigations carried out under EPRI contract RP2473-42, “Applications of static phase shifters for FACTS". Based on feasible semiconductor switches and converter topologies for high power applications, different static phase shifter (SPS) circuit configurations are identified and their operational principles are explained. SPS configurations are compared and their relative merits and/or limitations are highlighted. Two of the introduced SPS configurations provide two new layouts for retrofitting existing mechanical phase-angle regulators. A comparison paper examines technical performances of the SPS's for different applications
