Please suggest me suitable power electronics converter which can extract current of a particular frequency from a multi-frequency voltage bus at high power level.
Multi-frequency bus voltage
V = V1sin(w1t+phi1)+V2sin(w2t+phi2)+V3sin(w3t+phi3)+V4sin(w4t+phi4)
and I want a power electronics converter and load to connect across this voltage, but the converter should draw current of particular frequency only, say for example: i =I3sin(w3t+theta3), (see attached figure)
Please suggest me suitable power converter for this.
Is it possible to do so, without using passive LC filters?
instead of using Load you could re-inject the power to the main network with the same fundamental signal frequency and phase using DPC .
for high power level you could use multilevel converter.
you could also extract the current using DPC with some changes.
Active powe rfiltering and multi-level converters are both solutions. What is the rating of the converter?
Thanks Hamid Reza Baghaee for your support.
Please let me know how multi-level converters can be used to extract a particular frequency current from a multi-frequency voltage bus. I am using 250 W converter.
