Technical FAQs 4

Why is DC-link current ripple important in a five-phase inverter?

Therefore, a thorough analysis of the dc-link current and voltage ripples on the capacitor in a five-phase inverter is essential for both optimal capacitor design and accurate performance evaluation. For the capacitor, high-frequency dc-link current ripple is introduced due to the PWM of the inverter .

How DC-link current and voltage ripple affect inverter performance?

Abstract Inverter's performance and operating mode may be negatively affected by inverter input (dc-link) current and voltage ripple. It is a common experience that even theoretically balanced load...

Why do inverter switching actions reduce DC-link voltage ripple?

Consequently, the pulsating current flowing from the inverter to the dc source can be effectively reduced . This, in turn, mitigates the dc-link voltage ripple, ensuring a relatively stable dc-link voltage under inverter switching actions .

What is DC-link voltage ripple?

The dc-link voltage ripple is an important parameter in the design consideration of the dc-link capacitor.
