Question

Difference between symmetric and asymmetric multilevel inverter

Answer 1

Explanation:

Asymmetric multilevel inverter is same as symmetric multilevel inverter circuit configuration; the only difference is the dc link voltages.

Answer 2

Explanation:

Unlike the symmetric topology, the asymmetric topology must be able to bypass or conduct the dc voltage sources separately. This is necessary to generate all of the desired voltage levels. For this purpose, two additional switches are used to fulfill the requirement of an asymmetric multilevel inverter.
