Semiconductor device having a double-gate switching element |
摘要 |
A semiconductor device has a drive unit outputting a first drive signal to a first electrode and a second drive signal to a second electrode, an instruction signal generation unit generating an instruction signal as a basis of the drive signals and a control unit outputting a first control signal as a basis of the first drive signal and a second control signal as a basis of the second drive signal, based on the instruction signal to control the drive unit. The control unit synchronizes the first control signal with the instruction signal, delays a turning-on timing of the second control signal by a predetermined time relative to the instruction signal and determines a turning-off timing of the second control signal based on a previous pulse width of the instruction signal. |

1. A semiconductor device for driving a control electrode, which includes a first electrode and a second electrode in parallel, to control turning-on and turning-off of a switching element, comprising:
a drive unit for outputting a first drive signal to a first electrode and a second drive signal to a second electrode, to drive turning-on and turning-off of a switching element; an instruction signal generation unit for generating an instruction signal as a basis of the drive signals; and a control unit for outputting a first control signal as a basis of the first drive signal and a second control signal as a basis of the second drive signal, based on the instruction signal to control the drive unit; wherein the control unit synchronizes the first control signal with the instruction signal, delays a turning-on timing of the second control signal by a predetermined time relative to the instruction signal and determines a turning-off timing of the second control signal based on a previous pulse width of the instruction signal. |
