【 摘 要 】

The investigation deals with multi-motor electric drives with frequency converters of various structures: with a common converter, with an individual converter, with a multi-inverter frequency converter. Their shortcomings and advantages were analyzed and there were drawn conclusions about the expediency of using each structure. Expediency of using multi-inverter frequency converters with an active frond end was shown to ensure the highest power characteristics of multi-motor electric drives of drilling rigs' main mechanisms.
