Free QuoteWhen the available input voltage source is dc, the inverter's input voltage can be controlled by using a chopper. The block diagram for controlling the output voltage of the inverter when the input voltage available is constant is of constant DC type is shown below.
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.
In motor control applications, inverters handle the control of circuit voltage along with frequency so that the saturation of motor magnetic circuits is avoided. In the case of variable speed drives, inverters with voltage control help in achieving voltage variation.
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. The block diagram representation of this method is shown in the below figure.
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.
