Three-phase capacitor input diode rectifiers offer several advantages such as a simple topology, low high-frequency noise, high reliability, and high environmental durability. However, they produce undesirable lower-order harmonics in the input current. To overcome this problem, a three-phase diode rectifier without active switching devices or transformers is proposed, which meets the regulations of JIS C 61000-3-2 (Class A). In this paper, the proposed rectifier (7.0kW, 200V/50Hz) is validated through experimental results.
