- Abstract
- To ensure a high efficiency of a power factor correction (PFC) converter, the totem-pole bridge-less PFC (TBPFC) topology is proposed, replacing the diode rectifier stage with a power semiconductor switch. However, a current spike of an AC side may occur during rectification timing, so an appropriate control algorithm is required. This paper proposes a control algorithm for TBPFC, including DC-link voltage and inductor current control. The proposed algorithm has a simple control structure using a general proportional-integrator (PI) control structure and controls the power factor and output DC voltage simultaneously. The sensed input voltage value is used to define the low-speed switch leg operation and calculate the AC inductor current reference. The feed-forward duty is calculated to ensure the stable operation of the high-speed switch leg. The control algorithm is implemented through a control board based on TI's digital signal processor (DSP), and the hardware in the loop simulation (HILS) device is used for hardware simulation. The validity of the proposed algorithm is verified using PSIM simulation and HILS environment.
