What is voltage source inverter?

Definition: A voltage source inverter or VSI is a device that converts unidirectional voltage waveform into a bidirectional voltage waveform, in other words, it is a converter that converts its voltage from DC form to AC form. An ideal voltage source inverter keeps the voltage constant through-out the process.

Can an inverter change the amplitude of the output waveform?

The inverter can change the frequency of the output waveforms by changing the length of time that the switches are turned on. However, the amplitude of the AC waveform is determined by the DC input voltage. Thus, changing the amplitude of the AC voltage requires a variable DC input to the inverter.

What are the different types of voltage source inverters?

Voltage source inverters are generally classified into two types viz pulse width modulation and square wave. These inverters are introduced in early 1960’s during the introduction of force commutating techniques. The major disadvantage of this inverter is that the output voltage contains lower order harmonics for low or medium power applications.

How to wire a voltage source inverter?

For example, voltage source inverter uses an LC filter. The L2 and L2N slot must be jumper wired as shown in Figure 11. Ensure that the capacitor is 20 μF by checking the marking on the capacitor. Insert the control card in the J15-J16 slot. Insert a jumper at J10 if not already populated. Connect a 15-V DC, 1-A power supply at J2.
