A multiphase DC to DC converter includes an input, an output, at least
first and second converters, an inductor, an output capacitor, and a
drive circuit. The drive circuit is configured for switching the first
and second converters with a predetermined phase shift therebetween. The
output capacitor is operatively coupled between the first and second
converters and the output. The inductor can be placed either at the input
side or the output side. When placed at the input side, the inductor is
operatively coupled between an input capacitor and the first and second
converters. When placed at the output side, the inductor is operatively
coupled between the first and second converters and the output capacitor.
The multiphase DC to DC converter is capable of achieving lossless
switching transitions and negligible ripple current in the output
capacitor.
