This paper describes a control design methodology
based on output impedance analysis for multiphase synchronous
buck converters. This design leads to an optimal output voltage
transient response. Two design alternatives are proposed. The first
alternative uses an equivalent single-phase converter to design the
control parameters. This approximation is valid as long as the
deviations between the phases of the converter are within the usual
tolerance limits. The second one achieves exact constant resistive
output impedance regardless of the differences that exist between
the phases. Simulation and experimental results are reported in
order to validate the two design approaches.
