Ways to solve them are selected by using three-phase three-level voltage inverters with asynchronous electric motors as part of the traction electric drive of dual-system electric trains on railways. The following criteria were taken into account in the comparative analysis of the specified use cases: energy saving at the stages of production, operation and disposal; costs of production of new electric rolling stock; future operating costs; unification of electrical equipment of new electric rolling stock; application of environmentally friendly technologies.
