摘要：
Three-phase single-switch buck converters can be made to operate with a very good power factor if their input capacitor voltages are discontinuous. Operating these converters in discontinuous voltage mode (DVM), however, results in high peak voltages that cause the switch to have peak voltage stresses. In this paper, a variable switching frequency control technique that can reduce these stresses is presented and a comparative study between the conventional three-phase single-switch buck and the quadratic buck converters operating with this technique is made.
