Question

Advantages and disadvantages of voltage source inverter and current source inverter

Answer 1

Inverters are the sources to convert power from direct current(DC) to alternating current(AC). There are different types of inventors;

(i) Voltage Source Inverter(VSI): In this type of inverter the direct current remains constant. 
             
           Advantages: The advantages of VSI are;
                                (i) It has a small size. 
                                (ii) Its output voltage waveform does not depend on the                                         type of load. 

           Disadvantages: The disadvantages of VSI are;
                                   (i) Short circuit is not preventable. 
                                   

(ii) Current Source Inverter(CSI): In this type of inverter the direct current is to be maintained. 
     
           Advantages: The advantages of a CSI are; 
                                (i) Thyristor is used for commuting which is a simple                                             way.
                                (ii) The current flow is limited through safe value. 

          Disadvantages: The disadvantages of a CSI are; 
                                (i) It has unstable performance on light loads.
                                (ii) It requires an extra converter stages.
