Embodiment Construction
[0029] The content of the present invention will be described below in conjunction with specific embodiments.
[0030] Such as Figure 1 to Figure 3 As shown, it is a structural schematic diagram of a smoothing capacitor for an electric vehicle according to the present invention. A smoothing capacitor for an electric vehicle according to the present invention includes: a main capacitor bank 1 and two lead-out terminals 2 respectively connected to the two poles of the main capacitor bank 1, and two series connection terminals 2 are arranged between the two lead-out ends 2. Then Y capacitors 3 connected in parallel with the main capacitor bank 1, between the two Y capacitors 3 is a neutral point leading ground terminal 4. Specifically, the capacitance of the main capacitor bank 1 is 600 μF, the capacitance of the two Y capacitors 3 is 0.175 μF, and a discharge resistor R is also connected in parallel between the two poles of the main capacitor bank 1, and the discharge resistor...
