图1 使用这种低成本电路可驱动高端FET或IGBT。图1所示是可以为脉宽调制器与高端IGBT(绝缘栅双极三极管)或MOSFET开关之间提供接口的中小型电源系统。当采用ICL7667或MIC4423等FET驱动器作为缓冲器时,可以将其作为TTL或CMOS电路与H桥的接口。当OA为正时,D_1导
Figure 1 uses this low-cost circuit to drive high-side FETs or IGBTs. Figure 1 shows a small to medium-sized power system that provides an interface between a pulse-width modulator and a high-side IGBT (insulated gate bipolar transistor) or MOSFET switch. When using an FET driver such as an ICL7667 or MIC4423 as a buffer, it can be used as an interface between a TTL or CMOS circuit and an H-bridge. When OA is positive, D_1 guide
