Abstract:
A method and an apparatus for driving a power switch tube. The apparatus includes an input unit, a drive unit, a transformer and a power switch tube. The input unit is connected to the drive unit, which is configured to input a group of drive signals, and the group of drive signals includes four drive signals, where the first drive signal and the second are complementary signals, and a dead time exists; the third drive signal and the fourth are complementary signals, and a dead time exists; the phase difference between the first drive signal and the third is 180 degrees, and the phase difference between the second drive signal and the fourth is 180 degrees; the drive unit is configured to power on a field winding of the transformer; and the transformer provides a drive voltage signal for the power switch tube.
