Zusammenfassung: | The invention discloses a power tube driving control circuit suitable for a solid-state power controller. The power tube driving control circuit comprises a switch-on/off circuit, a driving protection circuit, a transient suppression circuit, a slow switch-on circuit, a current sampling circuit, a freewheeling diode D2 and an MOS (Metal Oxide Semiconductor) transistor M1. Through adoption of the power tube driving control circuit, wrong switch-on/off actions of the MOS transistor M1 caused by a wrong power-on sequence can be avoided, and the problems of poor capacitive load capacity, high dependence on a parasitic parameter, failure in normal startup due to large transient current, and the like in an existing solid-state power controller are solved. |
