The mode of model averaging is proposed which allows to analyze the processes at pulse dc converters from general positions. Obtained model contains both parameters of average variable states, their ripples during period of steady-state regime and parameters of time intervals of converter state. The range of ratio between time constant of converter circuit and its operation period is grounded in which the error of model calculations is not more than 3%. The calculations using proposed mode and method of schematic simulation are fulfilled by the example of simplest step-down converter that confirms the high precision of results coincidence at mentioned range of parameters. References 9, figures 2, table 1.


Key words: state-space averaging method, pulse dc converter.
