The reverse blocking IGBT for matrix converter with ultra-thin wafer technology

An isolation type vertical 600V-50A IGBT with reverse blocking capability (RB-IGBT) has been developed for the first time. Ultra-thin wafer technology combined with deep boron diffusion technique results in a great improvement on trade-off performance. RB-IGBT can be used as a bi-directional switch by anti-parallel connection with another RB-IGBT. These bi-directional switches realize a high efficiency matrix converter.
