Average Current Mode Control of a Boost PFC Converter Using Dual-Loop PI Compensators
ELK 453E · Istanbul Technical University
Designed and modelled a 500 W, 400 V, 50 kHz single-phase boost PFC converter using cascaded average-current-mode control with inner current and outer voltage PI loops. Component sizing, small-signal analysis, controller tuning, and model-based MIL/SIL/PIL verification produced a regulated 400 V output, a 0.99 power factor, and 4.48% input-current THD.
