Research on Peak‐to‐Average Power Ratio Control Method for Switched Reluctance Pulse Generator
IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.Addressing the different requirements for peak output power when SRPG supplies power to pulse loads and DC loads, the peak‐to‐average power ratio (PAPR) is taken as the generation performance optimisation parameter. By investigating the power characteristics of the SRPG, the influence of control parameters on the PAPR is studied.
