Title:
スイッチの駆動回路
Document Type and Number:
Japanese Patent JP7119872
Kind Code:
B2
Abstract:
A driver circuit works to drive a first switch and a second switch connected in parallel to each other. The driver circuit includes first and second charge switches and first and second diodes to turn on only one(s) of the first and second switches selected as an on-target(s). The driver circuit includes first and second individual discharging paths connected to gates of the first and second switches, first and second discharge resistors, a shared discharge path, and a shared discharge resistor. This structure is capable of reducing a switching loss.
