DB35-16, Three-Phase Bridge Rectifier for Wind Turbine Battery Rechargings

More independence through wind energy. However, as wind is not always available, wind energy storage systems stabilize the usability of this source. Surplus energy is stored for later use. Diotec's DB35-16 bridge rectifiers, three-phase rectifiers with a VRRM of up to 1,600V and an IFAV of up to 35A, play an important role here.

Diotec's DB35-16 bridge rectifiers, three-phase rectifiers with a VRRM of up to 1,600V and an IFAV of up to 35A, play an important role here. They are installed in the head of the turbine to store energy as an input stage for battery chargers. Powerful battery storage with up to 1.1 MWh capacity per container, transformerless inverters for higher efficiency, e-car battery modules, and the use of battery modules from the automotive industry. Remote maintenance through remote control software. The Schottky diodes SGL1-60 and SGL1-90 in the DO-213AA/MiniMelf housing are also used for output rectification in DC/DC and inverters, to protect against reverse polarity, and to reduce losses in power conversion systems due to their low forward voltage drop and fast switching characteristics.

An example: According to EnBW, "around 60 gigawatts (GW) of wind turbines are currently installed in Germany - an increase of 2.1 GW or four percent compared to the previous year".
