6 FAQs about [Inverter lc energy storage inductance calculation]

How do I choose the inductive reactance of a VSI inverter?

To answer this question, I would assume you have a simple 3-phase VSI inverter, grid-tied through an L-C filter. In this case, it is a popular practice to choose the inductive reactance to be 5-10 % of your base impedance rating (=Vgrid/Igrid) at the grid frequency.

What are some features of this inverter design?

This inverter design offers high-efficiency, low THD, and intuitive software. These features make it attractive for engineers working on an inverter design for UPS and alternative energy applications such as PV inverters, grid storage, and micro grids.

How do I adjust the active power of an inverter?

If you only want to adjust the active power, you may simply keep the inverter phase angle and fundamental frequency the same as that of the grid and only adjust the magnitude of fundamental voltage component on the AC side of the inverter (by adjusting the modulation index).

What are L2 and L2N in a voltage source inverter?

In a voltage source inverter, L2 and L2N are jumper wired components. The reference design and EVM box provide these components, with L2N needing to be soldered on by the user.

What inductor is used in the LCL filter?

For example, for the grid connected mode, an LCL filter is used. L2 and L2N must be populated with the 470-mH inductor. This inductor is provided in the EVM box, and the part number can also be identified from the BOM.

How do I calculate capacitance if I don't have L-C?

Once you have the inductance value, you can calculate the capacitance value depending on the THD requirement at the grid side (usually less than 5 %). If you do not have L-C and only have 'L', then the value will completely depend on the grid current THD - higher the inductance value, lower the THD.
