higher input voltage and lower output voltage, multiphase buck converter has a very small duty cycle, which compromises the steady-state and dynamic performances. To improve the efficiency without compromising the transient, this chapter proposes to use multi-winding coupled inductors in multiphase converters in order to extend their duty cycles.
