VRM, nonlinear control, fast transient response, DC/DC converter
A linear-non-linear digital control for multi-module DC/DC converters that improves system stability, solves the limit-cycle problem, reduces recovery time and limits overand under-shoots in regulated output voltage, is presented. A simulation model in MatlabSimulink/Active-HDL mixed environment is described. Preliminary hardware tests on a single-phase step-down converter are reported. Simulation and experimental results are shown.
