Technical FAQs 4

What is current source inverter (CSI)?

H.J. Kim In Current Source Inverter (CSI), the input side of the inverter is connected to a DC current source and hence, the polarity of the input current remains the same. The polarity of the input DC voltage, however, determines the direction of average power flow through the inverter.

What is a current source inverter?

Compared with the voltage source inverter, the current source inverter has the boosting characteristics, and the AC side does not need a complex and bulky filter unit, but it also has the problem of current control of the DC energy storage inductor.

What are voltage-source and current-source inverters?

Voltage-source and current-source inverters are depicted in Fig. 3, where V VS (s) and I VS (s) in Fig. 3 (a) represent voltage and current of the voltage source; while V CS (s) and I CS (s) in Fig. 3 (b) stand for voltage and current of the current source, respectively.

Are current source type inverters still used?

However, current source type inverters are still in use for some applications. For example, in high-voltage direct current (HVDC) transmission, a DC current travels a long distance before being converted back into AC. This means a DC current is supplied via a large reactor.
