Static Characteristics of Three-Phase Choke-Input-Type Diode Rectifier with AC-Side Inductors

Abstract

Three-phase diode rectifiers have several advantages, such as simple topology, low amounts of high-frequency noise, high reliability, and high environmental durability. However, these rectifiers produce undesirable lower-order harmonics in the input currents. To overcome this problem, a three-phase choke-input-type diode rectifier with AC-side inductors is presented here, which meets to the regulations of JIS C 61000-3-2 (Class A). In this study, the three-phase diode rectifier (3.0kW, 200V/50Hz) is validated through experimental results.
