story:
As demand of electrical devices steeply
increases, PFC circuits have drawn lots attraction to control harmonic
pollution on the power grid. So far, the conventional PFC control methods have
shown limited PFC performance, for example, increasing harmonic distortion
depending on load or input voltage variation. To overcome the problem, new
control methods have been proposed, which showed better performance, but are
relative complicated. Now, new modulated carrier control method is proposed to
provide high PF and low THD regardless of input voltage range and load
variation. This is realized and demonstrated in this paper.
