Abstract

Iterative learning based digital peak current mode control (PCMC) is proposed in this paper. The proposed control method provides excellent current reference tracking against variations in input voltage, load, and circuit parameters. Compared to other current control methods, the proposed digital PCMC has a high dynamic response, a simple structure and a low computational burden. It is suitable for power factor correction (PFC) converters operating at high frequency. Thanks to the iterative learning control (ILC), the peak current value in PCMC is successfully compensated against disturbances. The proposed new current control method is applied to an interleaved totem pole PFC (ITPPFC) circuit. The ITPPFC circuit prototype is implemented with 250 W output power and 100 kHz switching frequency. The circuit prototype is tested under various load conditions and parametric disturbances. Theoretical and experimental results are found to be consistent.
