Question

In current source inverters (CSIs), the output voltage’s

(a) amplitude depends upon the load impedance

(b) waveform depends upon the load impedance

(c) amplitude as well as the nature of the waveform depends on the load

(d) both amplitude and waveform are independent of the load impedance

The question was posed to me during a job interview.

I would like to ask this question from Current Source Inverters in division Inverters of Power Electronics

Answer 1

The correct answer is (c) amplitude as well as the nature of the waveform depends on the load

The explanation is: In CSIs, the amplitude of the output current is independent on the load impedance, as the input current (to the CSI) is kept constant. However, the magnitude of output voltage and its waveform depends upon the nature of the load impedance.
