Analysis and design consideration of the novel three phase converter with new bootstrap driver circuit for the mobile micro processor in the laptop PC are presented. The voltage conversion ratio of the proposed converter is one third of the duty cycle. The voltage across the switches during switching operation is one-third of the input source voltage. The current ripple of the output smoothing capacitor is the same as that of conventional five-phase buck converter. The current balance of the respective phases is automatically achieved without any current sensing means. The above fine characteristics are simply achieved with two additional capacitors.
