FAQs 6

How to control the output voltage of an inverter?

When 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.

How to control an inverter?

The aforementioned methods of inverter control require additional components to generate output voltage or the desired magnitude, phase, and frequency. Modulation involves adjusting the on and off duration of inverter switches under constant input DC voltage to achieve controlled inverter output voltage.

How a voltage control inverter helps in achieving voltage variation?

In the case of variable speed drives, inverters with voltage control help in achieving voltage variation. Voltage control of inverters is employed in order to compensate for changes in input dc voltage.

How do inverters satisfy AC load input requirements?

To satisfy AC load input requirements, inverters are controlled so that they supply the voltage in the desired magnitude, phase, and frequency. The inverter output voltage can be controlled in various ways. Modulation is an internal method of controlling an inverter to generate the desired voltage waveform.

What is inverter modulation?

Modulation involves adjusting the on and off duration of inverter switches under constant input DC voltage to achieve controlled inverter output voltage. The most popular modulation technique used in inverters is pulse width modulation (PWM). Space vector modulation is often used in inverters due to its ease of implementation.

Why are inverters used in motor control applications?

When inverters are used to feed such ac loads, it is necessary that the inverters provide provision for voltage variations so as to supply the required voltage to ac loads. In motor control applications, inverters handle the control of circuit voltage along with frequency so that the saturation of motor magnetic circuits is avoided.
