DRIVING CIRCUIT AND DRIVING METHOD FOR SWITCHING ELEMENT

A method of driving a switching element in a switching circuit, where the switching element comprises a plurality of power transistors coupled in parallel, can include: determining a state of a load in the switching circuit; decreasing a driving voltage of at least one power transistor in order to r...

Zusammenfassung:A method of driving a switching element in a switching circuit, where the switching element comprises a plurality of power transistors coupled in parallel, can include: determining a state of a load in the switching circuit; decreasing a driving voltage of at least one power transistor in order to reduce driving loss of the switching element when a load is in a first load state; and maintaining driving voltages of the plurality of power transistors at a first threshold when the load is in a second load state.
