Power devices for MW and GW power electronics are discussed. The most important device concepts of today are Phase Controlled Thyristor (PCT), Integrated Gate Commutated Thyristor (IGCT), Insulated Gate Bipolar Transistor (IGBT), and PIN diode. In spite of long-term intensive research of compound semiconductor materials and related devices, the world of high-power devices is dominated by silicon....
For the further improvement of today's full converter systems for windpower applications a 6 MVA converter prototype has been developed. It is utilizing the ANPC5L topology as inverter on the grid-side and the simple 2-quadrant ANPC3L topology as rectifier for a permanent magnet synchronous generator (PMG). ANPC stands for Active Neutral Point Clamped, which is the base for the derivation of multiple...
