The single phase boost PFC converter is used as a front end stage in equipments in order to conform to harmonic standards. Due consideration is to be given for the implementation issues in the boost PFC converter due to the large signal variations in the converter waveforms and its wide operating ranges. This paper highlights the practical challenges and implementation aspects with respect to the topology and control in a single phase boost PFC converter. The causes of input current distortion and conduction mode change are analysed. The effect of voltage loop bandwidth on the converter performance is discussed. Digital implementations with PI current controller and with predictive current controller are discussed. Inferences are presented based on equations and experimental results. The experimental tests are carried out on a 50 Hz universal AC input, 400 V DC output, 300 W single phase boost PFC converter hardware prototype operated at a switching frequency of 100 kHz.
