This document provides information on how to determine the output performance of the driver used to switch the IGBT.
The document provides methods for determining the performance of IGBT drivers used in power electronic systems. It covers gate‑charge curves, measurement techniques, driver output‑power calculations and selection criteria for suitable drivers.
The note also introduces the free DriverSel software tool for simplifying driver calculations and includes symbols, terminology and reference material for further study. This manual is written in Chinese.
The gate charge is determined by the equivalent input capacitances CGC and CGE.
Driver output power can be expressed with the formula shown as sw_out = GD f EP ×.
