Abstract
The size of the LCL filter can be decreased significantly using higher switching frequencies enabled by next generation semiconductors. This paper studies the effects of the switching frequency of a grid converter on the LCL filter design. The goal in the design is to minimize the stored energy of the magnetic components. The core material of the converter-side inductor is selected based on the highest peak flux density within core-loss density limits. A laminated iron-core inductor is assumed on the grid side. For achieving higher accuracy during optimization, the grid-side inductor is modelled using an analytical high-frequency model. The proposed design method is evaluated using a 50-Hz 12.5-kVA SiC grid converter as an example case.
