- Abstract
For problems such as the serious deviation of flying capacitor voltage of common-ground three-level Boost DC converter from 1/2 output voltage and high voltage stress for the switching device of the quasi-Z-source Boost DC converter, a novel quasi-Z-source three-level Boost DC converter is introduced. In order to realize the performances such as wide range of input voltage, fast response of output voltage and high efficiency of energy conversion, the simulation experiment is carried out by using interlaced modulation and phase modulation strategies. Through the comparison tests of the gain range, voltage stress, current stress and device selection, it is verified that the performance of the converter under the interlaced modulation strategy is better.
