4 FAQs about Three-phase inverter secondary ripple

Does a three-phase three-wire grid-tied inverter have a power ripple mitigation strategy?

Abstract: This letter proposes an active power ripple mitigation strategy for the three-phase three-wire grid-tied inverter. Under the unbalanced grid voltage scenarios, the double-line frequency oscillation will have occurred on the inverter output power and the dc-link voltage.

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.

Can DC-link ripple current minimization improve reliability of three-level voltage source inverters?

This paper proposes a DC-link ripple current minimization strategy to enhance the reliability of three-level voltage source inverters (3L-VSIs). The largest current among the three-phase currents flows through DC-link capacitors when a conventional space vector pulse width modulation (SVPWM) is applied to the 3L-VSIs.
