| Popis: |
In battery-fed PWM inverters, the DC-link capacitor represents a limiting factor in terms of power density. A proper DC-link capacitor design requires an accurate prediction of the DC-link voltage and current ripple. Unfortunately, only a small number of papers investigate the DC-link voltage ripple in battery-fed PWM inverters. Thus, this paper proposes a fast and accurate calculation method for predicting the DC-link voltage ripple in battery-fed pulse width modulated two-level three-phase voltage-source inverters. Based on the proposed calculation method, parameter studies are performed demonstrating that the battery inductance and resistance have a non-negligible impact on the DC-link voltage ripple. |
