Abstract: The article presents the results of the analysis of energy processes in the studied compensating converter at a four-fold frequency of transistor control pulses. The presence of three operating modes differing in the pattern of change in the phase current of the capacitor battery is revealed. One of these modes is studied in detail. A new scientific result is obtained. It shows that in the case when the commutating process in the power electric valve of one phase occurs in the operating interval of the transistor of the commutating link of the next phase, the value of the commutating voltage at the moment of commutating does not depend on the delay in supplying control pulses to the transistors. To confirm and verify the obtained results, circuit simulation in the Micro Cap package is used. The modeling technique is described, its results are presented, and the results are analyzed. A comparative analysis of the numerical values of the characteristics of the energy processes of the studied converter obtained as a result of analytical calculation and circuit simulation showed that the discrepancy does not exceed 4%. This indicates the adequacy of the applied modeling technique and acceptable accuracy of the results of analytical calculations. Refer. 6, fig. 4.
