Abstract
The switched reluctance machines (SRM) in most cases of their application do not have a galvanic connection between the phase windings. It is widely known when one phase fails, SRM as a short circuit in the coil of one of the phases, the others continue to work. This gives you the ability to retain partial performance of the engine. This is especially important for transport systems: an electric car can drive to a depot on its own, and an electric car can drive to a service station. And for some transport systems, such as manned underwater vehicles, maintaining partial performance in emergency situations is a priority requirement-the life support of the crew depends on it.For using a widely applied semi-bridge power supply scheme, the SRM with two transistors for each of the phases of the electric motor, it is not possible to maintain partial performance of the SRM if the only power source fails. To ensure the performance of the type, in the case of a short circuit in the source, a new power supply scheme for the SRM is proposed, containing one transistor for each of the phases of the engine (patent No. 2704494). Each phase is electrified charged from a separate source. For transport systems that have batteries in their composition, the total battery is divided into components by the number of phases. At the same time, the entire electrical circuit of the SRM phase, including the source, is backed up.A simulation of the proposed new power supply circuit was performed in order to confirm its performance and evaluate its functionality. The analysis of the existing Converter circuits used for SRM is carried out, which allows to evaluate the advantages and disadvantages of the proposed circuit solution.
