Digital Driver Core to Control IGBT Power Semiconductors
Power electronic systems in the voltage range of 1200V and higher call for fully insulated signal transmission for both PWM and IGBT status signals. In order to achieve sophisticated and repetitive signal transmission for all signals, including sensing signals, a fully digital driver core solution was developed to drive and control IGBT power semiconductors. This paper describes the characteristics and advantages of insulated digital signal transmission in comparison to analog signal transmission and explains the direct link between controller and gate driver interfaces. On the basis of an eye diagram, a qualitative analysis of digital transmission is shown. Furthermore, the performance of a digital-based driver core solution is evaluated.
