| Summary: | The performance of electric drive system for electric vehicle largely depends on the characteristics of DC-link capacitor
in inverter, especially the abilities to absorb ripple current and ripple voltage of DC-link. Research on the ripple status of capacitor under
different driving conditions is better for the optimal selection of capacitors and the reliability of driving system. Based on the SVPWM
modulation mode and its latent modulation wave function, the calculation formulas of ripple current and ripple voltage of DC-link capacitor
were deduced and analyzed under different operation conditions. |
