A recently proposed third harmonic injection rectifier (two half-bridge legs) - serving as optional solution for passive three-phase diode bridge systems with LC output filter - is characterized by unity power factor (λ ≈ 1) and low harmonic input currents (THD < 5%). The rectifier at hand, furthermore sticks out of the crowd due to a very low number of active and passive switches compared to similar power electronic circuits based on the same (third harmonic injection) principle. Additionally, the more and more establishing and reliable SiC-MOSFET allows an optimizeddesignforhigherswitchingfrequencieswithoutseriously impairing the efficiency of the total system. A proper design of active and passive components of the optional circuit is therefore requiredandseveraloperatingmodesandoptimizationpossibilities are existing.
