WebAug 10, 2024 · Also, fast decay mode can reduce power dissipation if the on-state resistance of the FETs results in a voltage drop that is lower than the forward voltage of the diodes. Figure 4. As an alternative to fast decay mode, you can use body diodes or external flyback diodes to provide a path for the decaying inductive current. Webdrive the IGBT and are used to calculate values like average drive voltage and the driving electric power. Fig.7-4 shows the circuit schematic as well as the voltage and current waveforms. In principle, a drive circuit has a forward bias power supply alternately switching back and forth using switch S WebWhen the voltage across the p-n junction is in the correct direction, a significant current flows and the device is said to be forward-biased.
