The power supply system includes a converter converting a direct input current into a polyphase alternating output current including a plurality M of phases. The converter includes two input terminals, is arranged at the input of the element and delivers the polyphase alternating current to element. The power supply system also includes a controller controlling the converter, a storage bank including at least one storage capacitor between the input terminals, a device protecting the element from over-voltages or over-currents of the polyphase alternating current, between the converter and element, including a plurality of switching arms between the respective phases of the polyphase alternating current. Each switching arm includes two thyristors connected head-to-tail and in parallel. The controller applies a negative voltage to the terminals of at least one thyristor during a period greater than a predetermined turn-off time of the thyristor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply system for an element, among a rotor and a stator of an electric machine, and method for controlling such system","description":"A power supply system is provided.
