Results of modeling and calculation of parameters down and step-up DC switching converters are given. It is shown that the NI Multisim package contains rather exact and adequate models of radioelements and it can be successfully used for circuitry modeling of pulse devices of secondary power supply. 

Keywords: circuit simulation, a voltage regulator, pulse width modulation, the conversion constant voltage switching regulator.
