Title:
MILLER CLAMPING DEVICE FOR PARALLEL SWITCHING TRANSISTORS AND DRIVER COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2022/048629
Kind Code:
A1
Abstract:
The present invention provides a Miller clamping device for parallel switching transistors and a driver comprising same. The Miller clamping device comprises: a driver chip comprising an output terminal and a built-in Miller clamping circuit having a Miller clamping terminal, the output terminal of the driver chip being configured to output a pulse width modulation signal; and a plurality of auxiliary Miller clamping circuits, each of the auxiliary Miller clamping circuits being connected between a gate of a corresponding switching transistor and the Miller clamping terminal of the built-in Miller clamping circuit. When the built-in Miller clamping circuit is triggered for Miller clamping, Miller current generated by the corresponding switching transistor flows to a first direct current voltage by means of the corresponding auxiliary Miller clamping circuit. The Miller clamping device in the present invention can perform Miller clamping on parallel switching transistors and reduces circuit cost.
