| Abstract |
In order to provide the power to the microprocessor, a novel two-phase converter with the large step down conversion capability is presented. The voltage conversion ratio of this converter is given as Eo/Ei = D/2. The switching loss and the output voltage ripple are also reduced. Moreover the current unbalance between two inductors in each phase is removed automatically without any current sensing means. |
