Special Question Of Electrical Machine

December 28, 2024

Q1) In CSI if the frequency of output voltage is f Hz, then the frequency of voltage Input to CSI is -

a) F
b) 2F
c) F/2
d) 3F

Solution

Refraction of light

Current source inverter:

Reflection of Light

  • The current source inverter converts the input direct current into an alternating current.
  • In the current source inverter, the output current remains constant with respect to the type of load.  
  • The function of the inductor LS is to decrease the ripple in the source current.
  • The input frequency (fin) in a current source inverter is twice the output frequency (fo).

Calculation:

Given, fo = f 

fin = 2fo

fin = 2f
