| description | The utility model provides an electric automobile, a motor controller and a printed circuit board thereof, and the printed circuit board comprises a substrate; wherein the voltage sampling circuit isarranged on the substrate; the voltage sampling circuit comprises a first voltage dividing unit, a second voltage dividing unit and a signal processing unit. The input end of the first voltage dividing unit is connected with a positive direct-current bus, the input end of the second voltage dividing unit is connected with a negative direct-current bus, and the output end of the first voltage dividing unit and the output end of the second voltage dividing unit are both connected with the signal processing unit. The wiring of the interference source passes through the area where the input end ofthe first voltage dividing unit is located. Therefore, the voltage sampling circuit layout of the printed circuit board can be optimized, interference of an interference source such as switching waves of a power switch on vol |
