3 FAQs about Brasilia demonstration solar-powered communication cabinet inverter connected to the grid

What is the control design of a grid connected inverter?

The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.

What type of modulation is used in an inverter?

This reference design uses a modified unipolar modulation in which switches Q1 and Q2 are switched at a high frequency and switches Q3 and Q4 are switched at a low frequency (frequency of the grid). Table 2 lists the switching states of the inverter.

How do I create a plant model for the inverter?

The plant model for the inverter for the output current loop is created using the parameters specified on the powerSUITE page. If a change is required to resonant and PI controller, close the compensation designer and edit the values on the powerSUITE page. Save the page. Relaunch the GUI.
