A power factor correction (PFC) technique based on pre-calculated duty cycle values is presented in this paper. In this method the duty ratios for half a line period are calculated in advance and stored in a memory. By synchronizing the memory with the line, near unity power factors can be achieved in a specific operating point. The main advantage of this technique is that neither current measurement nor current loop are needed. To obtain stable output voltages a voltage loop is included. A boost converter prototype controlled by an FPGA evaluation board has been implemented in order to verify the functionality of the proposed method. Both the simulation and experimental results show that near unity power factor can be achieved with this PFC strategy.
