Abstract
The converter topologically conjugates with its symbolic time series by mathematical demonstration, the time series of converter are translated into symbolic series based on return map. This study takes one-order DCM Boost as examples, time irreversibility and block entropy of different word lengths in DC-DC converters are analyzed by using coarse-grained discretization. Reasonable coding method of symbolic series is determined from statistics perspective, which can provide theory basis for digging into nonlinear characteristic and chaos in DC-DC converter.
