Technical FAQs 4

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.

Can SiC MOSFET be used in a full bridge type inverter?

By using SiC MOSFET as the switching devices in the full bridge type inverter circuit, the conversion efficiency can be substantially increased even though the switching operations are performed at a higher frequency compared with Si IGBT.

Can a grid connected inverter be left unattended?

Do not leave the design powered when unattended. Grid connected inverters (GCI) are commonly used in applications such as photovoltaic inverters to generate a regulated AC current to feed into the grid. The control design of this type of inverter may be challenging as several algorithms are required to run the inverter.

Can Si IGBT/SiC MOSFET hybrid modules be used in three-phase grid-connected inverters?

This study investigates the application of Si IGBT/SiC MOSFET hybrid modules in three-phase grid-connected inverters, focusing on the relationship between the switching frequencies of Si IGBT and SiC MOSFET in the hybrid modules and the impedance characteristics of the inverters.
