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.
What are inverter standards?
Standards provide specifications for evaluating the durability and reliability of inverters, addressing factors such as thermal performance, mechanical resilience, and energy efficiency.
What is a typical inverter?
A typical inverter comprises of a full bridge that is constructed with four switches that are modulated using pulse width modulation (PWM) and an output filter for the high-frequency switching of the bridge, as shown in Figure 1. An inductor capacitor (LCL) output filter is used on this reference design.
How do you operate a DC inverter?
Observe that the current supplied by the DC source at the output decreases, and the inverter supplies the rest of the DC current. As this is DC operation, the inverter operates in buck mode. Increase the DC bus to 380 V. Maintain the closed loop operation as the user raises the DC bus.
