A Study on the Transient Responses of a Single-Phase Passive PFC Rectifier for European Use

Single-phase capacitor-input diode rectifiers have several advantages, including simple topology, low high-frequency noise, high reliability, and high environmental durability. However, these rectifiers produce undesirable lower-order harmonics in the input current. To overcome this problem, the authors proposed a new single-phase capacitor-input diode rectifier that meets the harmonic limits specified in “IEC 61000-3-2 (Class A)”. In this letter, the transient responses of the proposed rectifier were evaluated based on experimental results from a functional prototype, and it was confirmed that no overvoltage or overcurrent conditions occurred in the passive components.
