Voltage source inverters (VSIs) are commonly used in uninterruptible power supplies (UPS) to generate a regulated AC voltage at the output. Control design of such inverter is challenging because of the unknown nature of load that can be connected to the output of the inverter.
Basically, there are three techniques by which the voltage can be controlled in an inverter. They are, Internal control of Inverter. In this method of control, an ac voltage controller is connected at the output of the inverter to obtain the required (controlled) output ac voltage.
Enter 60 Hz for frequency for the AC waveform. This will be the frequency of the inverter output. Under Inverter Power Stage Parameters, enter 110 VRMS for the output voltage. This will be the value that the AC output will regulate to. Type Ctrl+S to save the page. Right-click on the project name. Select Rebuild Project.
To stabilize the output voltage of the inverter, we used a Proportional, Integral, and Derivative control (PID), which makes it possible to generate the necessary control signal for the voltage boost in order to have a good regulation of the output voltage of the inverter.
Voltage control of inverters is employed in order to compensate for changes in input dc voltage. Basically, there are three techniques by which the voltage can be controlled in an inverter. They are, Internal control of Inverter.
In this, the inverter circuit is fed from a constant dc voltage source and a controlled ac voltage is obtained at the output terminals by turning ON and OFF the switching components in the inverter circuit. The main drawback of this method is that it requires very low turn-ON and turn-OFF time thyristors which are very expensive.
