High dv/dt
WebPower switches with high dv/dt and di/dt rates like IGBTs are the source of EMI. The paper presents investigations of conducted EMI on IGBTs in different test circuits. Moreover, results are explained from a special developed model for prediction of common and differential mode interferences, that is suitable to determine solutions for a better EMC WebThese are trigger voltage and current, holding current and dV/dt. The basic properties of silicon are the same for thyristors as for ordinary diodes. However, the thyristor construction is a p-n-p-n sandwich between its main terminals, so the forward voltage drop is higher than that of an ordinary diode, generally from 0.8 to 2 V depending on current.
