4 FAQs about Inverter AC ripple current size

What is the output current ripple of inverters?

Regarding the output side of the inverters, the output current ripple is studied in terms of root mean square (RMS) minimisation and its maximum peak-to-peak value [4 - 7].

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...

What is a current ripple?

The current ripple can be seen as an integral of the instantaneous voltage difference between the output voltage and the sinusoidal reference voltage in (1). This expression, neglecting the voltage drop on the resistance (R), can be written as: where îx is the switching current ripple component and vx is the instantaneous voltage.

Are 'balanced' grid voltages considered in current ripple analysis?

Focusing solely on grid-connected applications, ‘balanced’ grid voltages have been considered in the current ripple analysis for both phase and neutral findings. Due to small ac coupling reactance (usually 0.05–0.08 p.u.), relevant unbalanced currents can be driven by slightly asymmetric inverter voltages.
