International Rectifier AN-978 RevD Application Note
The document provides a comprehensive guide for using the AN‑978 RevD high‑voltage floating‑gate driver IC. It covers gate‑drive voltage requirements, typical circuit topologies, bootstrap component selection, power‑loss calculations, handling of VS negative transients, PCB layout recommendations, and troubleshooting tips.
Key sections include high‑end device gate‑drive requirements, typical structure diagrams, methods to increase gate‑drive current, continuous gate‑drive provision, negative gate‑bias generation, driving buck converters, dual‑active‑bridge and switched‑reluctance motor drives, full‑bridge with current‑mode control, brushless and induction motor drives, push‑pull configurations, high‑end P‑channel operation, and a detailed fault‑diagnosis guide. This manual is written in Chinese.
Covers: High‑end device gate‑drive requirements · Typical structure diagram · Bootstrap component selection · MGD power‑loss calculation · VS negative transient handling · PCB layout and general considerations
