Current source inverters and voltage source inverts can seen in below figure. In case of the current source inverter, the rectify is linked with the inverter through the large series inductors Ls. The SCR current output signal is a square signal because the current passing is restricted to has a constant value.
The frequency converter with voltage source inverter will impose a voltage on the motor. Depending on the load the motor current will regulate itself. With an inverter of the current source type a constant current is imposed on the motor. Fig. 20-89 shows the switching matrix with associated switch currents and line currents.
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.
A Voltage Source Inverter (VSI) is an electronic device that converts a fixed DC voltage into a controlled AC voltage with adjustable frequency and amplitude. VSIs are characterized by their ability to maintain a constant voltage at the input while varying the output voltage and frequency as needed. Key Characteristics Input: Constant DC voltage.
