Abstract
Disclosed are a Miller Clamp protection circuit, a driving circuit, a driving chip and an intelligent IGBT module, which are connected to a device to be driven. The Miller Clamp protection circuit comprises a main driving circuit configured to provide a driving signal; a Miller switch configured to reduce a voltage glitch; a Miller switch control circuit configured to automatically control an on and off of the Miller switch according to an intermediate signal of the main driving circuit. The main driving circuit is connected to a power supply, the Miller switch control circuit, one end of the Miller switch and the device to be driven, and another end of the Miller switch is grounded.
