Abstract :
We propose a simple DC voltage sensor-less single phase PFC converter by detecting a AC line voltage waveform. Any DC
voltage and AC current sensors used in the conventional PFC converter are not required to construct the control system. The
conventional converter circuit with a boost chopper circuit in the DC side from a rectifier circuit is used as the main PFC converter
circuit. In the control system, the circuit parameters such as a series inductance L and equivalent load resistance value R are used
to generate the sinusoidal current waveform. The DC voltage is directly controlled by the command input signal kd (Ea/Ea) for the
boost chopper circuit. The DC voltage regulation is small because of the feed forward control for the AC line voltage Ea and no
dependence of the circuit parameters. The sinusoidal current waveform in phase with the AC line voltage can be obtained. The
feasibility of the proposed control system is verified by some simulation and experimental results. 6 Refs.
