Question
Asked 14th Feb, 2019

What are the relevant EMC/EMI Standards for inverters ?

I'm currently designing a single-phase VSI (for a non-industrial environnement) with taking into account EMC constraints (Emission only). What are the relevant EMC standards for such design and application ?

For welding machines, the standard for irradiated and conducted electromagnetic emissions is regulated by the international standard IEC 60974-10: 2014 with related attachments such as IEC 61000-3-12: 2011 which determines limits for harmonic currents produced by equipment connected to public low-voltage systems with input current >16 A and ≤ 75 A per phase

How to calculate the ∆i_max maximum current ripple for converter during LCL filter design for three phase VSC?

LCL filter are used for grid connected three phase inverters. The design of LCL filter is tricky as it can effect the stability of the system. During the design of LCL filter, to calculate converter side inductor, first maximum current ripple is calculated as
∆i_max=V_dc/(6L_i f_sw )
In above equation both ∆i_max and Li are unkown, so some authors[1] suggest to use 10% of Imax for this ripple current. On the other hand, other paper for example [2] and [3] use a relatively complex method to calculate the value of ∆i_max.
My first question is how accurate is use of 10%*Imax approximation? Are there any other quick way or approximations according to standards to find ∆i_max.
My second question is how to find the right attenuation factor δ for particular value of THD?
