Automatic Redundant Power Supply System for the Dynamic Braking System, Used for the Quick and Controlled Stopping of Wound-Rotor Asynchronous Power Motors, Specific to the High Power Testing Laboratories

Starting from the importance of fast and controlled braking of wound-rotor asynchronous motors, specific to high power testing laboratories, this article proposes an automatic redundant system for the dynamic braking system, used to stop under maximum safety conditions the asynchronous power motors, which use a hybrid photovoltaic panel system as main power source for charging the 240[V]DC/800[Ah] stationary battery, and an automatic three-phase rectifier as a redundant source. It describes the components, numerical simulations for the photovoltaic power system, as well as specific oscillograms during braking of asynchronous power motors in a High Power Testing Laboratories.
