Driving circuit for power switching device |
摘要 |
A driving circuit has a p-channel transistor and an n-channel transistor. A power switching element is set at an on state each time the p-channel transistor sets a charging line at a conductive state in response to a leading edge of an output pulse to supply a positive charge to a gate of the element through the charging line. The element is set at an off state each time the n-channel transistor sets a discharging line at a conductive state in response to a trailing edge of the output pulse to discharge the supplied charge through the discharging line. A through current occasionally flows through the transistors set at the on state together. The driving circuit has resistors between the transistors to suppress the through current.
