A Practical Tutorial on an IGBT Drive

This study presents a comprehensive and economical implementation of a drive circuitry for IGBTs based on the bootstrap technology. The drive is designed for medium power levels. The circuit includes desaturation and short circuit current detection. The development of the drive is explained from a practical standpoint, and the design is implemented on a circuit board and evaluated through laboratory experiments. The experimental results show that the designed circuit performed according to the specifications.
