Drive Pulse Generation

Posted on 21 April 2019

              Integrated circuits which are used for drive pulse generation, phase comparison with the terminal voltage, synchronisation and so on, facilitate driver design considerably. Owing to the power that can be dissipated by an integrated circuit (IC), however, it is not possible to extract a drive pulse with sufficient [...]

Towards a Clear Signal

Posted on 06 May 2019

  Driver circuit in digital technology controls IGBTs in the high-voltage range Power systems in the voltage range of 1200 V and higher require fully insulated signal transmission for pulse width modulation and IGBT status signals. With the aid of a driver circuit for controlling IGBT modules and high-voltage applications that is fully digitalised for [...]

600V SOI Gate Driver IC with Advanced Level Shifter Concepts

Posted on 03 September 2019

  Advanced Level Shifter Concepts for Medium and High Power Applications An advanced level shifter topology allows any desired reference voltage drop between the primary side and the secondary sides of a high voltage IC (HVIC), including negative voltages caused by parasitic elements. This makes the HVICs suitable for medium and high power applications. For [...]
