Drive circuit (voltage-type)

Published:2011/3/24 22:24:00 Author:muriel | Keyword: Drive circuit , voltage-type

Drive circuit (voltage-type)
(a)as shown the drive circuit suitable for low frequency miniwatt drive, when the control signal Ui is high level, VT1 breakover, output voltage Uo corresponding control switch tube (IGBT) is breakover; When the control signal Ui is low level, VT2 breakover, output voltage Uo corresponding control switch tube (IGBT) be turn off. (b) the drive circuit is shown by mosfet composition push-pull circuit, its working principle as figure (a) shows circuit. This circuit of high frequency peak value drive current can reach l0A above, it is suitable for high-power IGBT devices. (View)
