In this paper, a multiphase sliding mode (MPSM) control method with a master–slave

structure is proposed and analyzed in order to suppress ripples at input terminals or output terminals

in DC/DC converter applications. With the proposed MPSM, the switching frequency of a multiphase

DC/DC converter does not need to be operating such a high switching frequency as adopted in a

conventional sliding mode control-based DC/DC converter. As a result, switching power losses could

be reduced in this converter. Another advantage of this proposed method is that the master–slave

multiphase slide control loop could figure out a proper phase shift between each switching phase

of a DC/DC converter instead of precalculated phase shift. The proposed concepts are proven by

the PSIM computer simulations and the feasibility of the proposed concepts is validated through the

test experiments.
