Output voltage and power limits in boost power factor corrector operating in discontinuous inductor current mode

In this paper, there is shown the existence of limits to output voltage and power in a boost power factor correcting circuit operating in discontinuous inductor current mode. Like in a continuous case, the limits result from input current distortions that appear when the output power and voltage are not chosen properly for given circuit elements. There are presented graphs and numerical data which allow determining the proper values df circuit parameters and elements to ensure the proper operation of the whole circuit.
