How can I control AC voltage in an inverter?
To control AC voltage in an inverter, an ac voltage controller is connected at the output of the inverter to obtain the required (controlled) output ac voltage. This is one of the three techniques for voltage control in inverters, known as Internal control of Inverter.
What is the purpose of voltage control in inverters?
Voltage control of inverters is employed in order to compensate for changes in input dc voltage. In the case of variable speed drives, inverters with voltage control help in achieving voltage variation.
What does an inverter control in motor applications?
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.
What is a voltage source type inverter?
Voltage source type inverters control the output voltage. A large-value capacitor is placed on the input DC line of the inverter in parallel. And the inverter acts as a voltage source. The inverter output needs to have characteristics of a current source. In the case of low impedance load, series reactors are needed for each phase.
What are the three techniques to control voltage in an inverter?
Basically, there are three techniques by which the voltage can be controlled in an inverter. They are, Internal control of Inverter, External control of Inverter, and Natural control of Inverter.
