Can DC-link voltage ripple be analyzed for a non-electrolytic DC-link capacitor three-phase inverter?
To avoid these disadvantages, the DC-link voltage ripple must be fully analyzed for a non-electrolytic DC-link capacitor three-phase inverter. This paper presents the voltage ripple analysis of the voltage source inverter under the modulation methods of SPWM and SVPWM.
Why is current ripple important in three-phase PWM voltage source inverters?
Abstract — Determination of current ripple in three-phase PWM voltage source inverters (VSI) is important for both de-sign and control purposes, since this is the most popular conver-sion topology for energy conversion systems.
What happens if a capacitor has a large ripple voltage?
Having a large, lower frequency ripple current going through the capacitors can cause excessive heating of them and lead to a reduction in life. You can tell roughly how much current is going through those capacitors by looking at the ripple voltage at the converter DC terminals. Thus a large ripple voltage at that point is undesirable.
What causes a voltage ripple on a DC-link capacitor?
For a conventional hard-switching three-phase voltage source converter, the DC-link capacitor should be big enough to mitigate the voltage ripple to a tolerable value. Generally, two reasons will cause the voltage ripple on the DC-link, one is the pulsating current at the switching frequency which will cause high frequency voltage ripple.
