Abstract

See full text

The present invention provides a Miller clamping device for parallel switching transistors and a driver comprising the same. The Miller clamping device includes: a driver chip including an output terminal and a built-in Miller clamping circuit with 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, a Miller current generated by the corresponding switching transistor flows to a first direct-current (DC) voltage through a corresponding auxiliary Miller clamping circuit. The Miller clamping device of the present invention can perform Miller clamping on the parallel switching transistors and reduce the circuit cost.
