DGC （DYNAMIC Gate Controller）控制模块
Dynamic Gate Controller (DGC) - A New IGBT Gate Unit for High
Current / High Voltage IGBT Modules
1 Introduction
The “Dynamic Gate Controller” (DGC) represents the forth generation of intelligent IGBT
driver concepts. The DGC is especially designed to drive and to protect high-power IGBTs as
well as to simplify the construction of complete IGBT power stages.
The DGC concept is suitable for applications characterised by the following criteria:
A perfect protection of the IGBTs with very short delay and switching times
High PWM carrier frequencies at minimised dynamic power losses of the IGBT
Low EMI/RFI emissions at a high switching speed (high dv/dt and di/dt slopes)
A perfect driver and protection circuit for high-voltage IGBTs (Vces > 1600 V)
In contrast to high-power inverters u
