Abstract
A novel two-phase buck converter with two cores and four windings is proposed. In this converter, a capacitor is added to the primary side for dividing the input source voltage into one half in the similar way as that of a typical half bridge converter. The voltage conversion ratio is given as one fourth of the duty cycle with unity turns ratio of the each transformer. The output capacitor ripple and the switching losses are well reduced. The currents in each phase are balanced automatically without any current sensing methods.
