Abstract
A controlling apparatus for gate driving signal controls a gate of a power unit through a photo coupler includes a processor, a gate-controlling IC electrically connected to the processor and sending a gate driving signal of the processor to the gate, a transistor switch electrically connected to the photo coupler, and an isolation multiple input unit. The isolation multiple input unit has one output end connected to the processor, and connected to the gate-controlling IC through a hardware enable jumper. The transistor switch is controlled by a second control signal to turn off the gate. When hardware enable jumper is removed, the isolation multiple input unit is able to disable the gate-controlling IC for safety concern. When safety is not concern, the hardware enable jumper can be mounted to enable the gate-controlling IC. At this moment, the isolation multiple input unit can provide addition input.
