| Zusammenfassung: | The current detection system comprises an amplification circuit, a filter circuit and an analog-to-digital conversion circuit which are connected in sequence, the amplification circuit comprises an operational amplifier, a first resistor, a second resistor and a third resistor, the positive input end of the operational amplifier is connected with the input end of current to be detected through the first resistor, and the negative input end of the operational amplifier is connected with the output end of the current to be detected through the third resistor. The positive input end of the operational amplifier is connected with a power supply end through the second resistor, the negative input end of the operational amplifier is connected with a grounding end through the third resistor, the power supply positive input end of the operational amplifier is connected with the power supply end, and the power supply negative input end of the operational amplifier is connected with the grounding end. The output end of |
