Abstract
An electrical system for starting an engine is provided. The system includes: an AC/DC rectifier powered by an AC power network to deliver a first DC voltage V, a DC/AC converter module for delivering an AC voltage for starting the engine from said first DC voltage V, and k n-phase inverters arranged in parallel (k>1) and each delivering power no greater than half a maximum power Prequired for starting the engine, and the two power supply lines of each of the inverters are connected to an electronic protection device receiving the first DC voltage V, and the n outputs of each of the inverters delivering the AC voltage for starting the engine via n respective series inductors.
