The study presents a wind generator system based on a new converter configuration with a rectifier with near sinusoidal input currents (RNSICs-1 converter with DC capacitors connected in parallel with diodes). A detailed analysis of the system for different values of the load current is presented and the advantages of the solution are emphasised. The new converter configuration is characterised by smaller power losses, reduced electromagnetic interference (EMI) problems, low harmonic input currents, high reliability, as well as reduced costs. This original configuration could also be used for small hydro interconnection with squirrel cage induction generator (SCIG) and partial variable-speed wind turbine (typically 60–100% synchronous speed).
