STARTER-GENERATOR SYSTEM OF A MULTI-ENGINE POWER PLANT Russian patent published in 2022 - IPC F02N11/08 H02J9/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and power electronics, in particular to starter-generator systems of vehicles with internal combustion engines, and can be used to start primary heat engines and to generate electricity in power supply systems used in aircraft, ships, other vehicles and standalone objects. The effect is achieved by the fact that two voltage inverters and new connections are added to the starter-generator system of a multi-engine power plant, which make it possible to implement two electrically independent channels for starting primary heat engines with the subsequent possibility of extracting energy from them and generating electricity, as well as converting it to the required parameters electricity to supply electrical consumers at an autonomous facility. The positive effect of the proposal lies in the fact that with a minimum number of simple components of the starter-generator system of a multi-engine power plant and their possible combination by means of switching elements, when configuring the circuit, an improvement in operational characteristics, an increase in operational reliability, and an expansion of functionality are provided. In addition, the proposed structure makes it possible to use any type of AC electrical machines as electromechanical energy converters.

EFFECT: increasing reliability, as well as expanding the functionality and implementation of two galvanically isolated electrical networks with the possibility of both stabilizing the parameters of electricity and their software change independently for each of the electrical channels.
