Abstract
  A novel DC/DC converter for wide input voltage integrated Buck-Boost and series resonant converter which is applicable for wide input voltage was proposed. To reduce the conduction losses, the intermediate leg is shared in this topology. With the modulation strategy of PWM + Phase-Shift, constant output voltage and zero voltage switching of switches are realized. Six operation modes for above resonant frequency operation were analyzed in detail. The parameter design and zero voltage switching of the converter were researched. Simulation results with an IBBSRC model were shown to verify the validity and feasibility of the proposed circuit topology.
