Technical FAQs 4

What is a current source type inverter?

Current source type inverters Current source type inverters control the output current. A large-value inductor is placed on the input DC line of the inverter in series. And the inverter acts as a current source. The inverter output needs to have characteristics of a voltage source.

How do voltage source type inverters work?

It is easier to obtain a regulated voltage than a regulated current, and voltage source type inverters can directly adjust the voltage applied to a load by varying the conduction ratio (i.e., the pulse width of a PWM signal).

What are two-level current source inverters?

These are some examples of two-level current source inverters, but there are other variations and configurations possible. Two-level topologies are simpler than three-level topologies, but can produce a voltage waveform that is less smooth and has more harmonics.

What is a current source inverter (CSI)?

Low current and voltage harmonics. One of the topologies that has gained an increasing importance in the field of PV systems is the current source inverter (CSI). CSIs offer several advantages over other inverter technologies, making them a popular choice for both residential and utility-scale PV installations.
