Draw all the existing popular topologies for transformerless inverters and why were they developed

Question

Accepted Answer

Transformerless inverters have various popular topologies developed to meet different requirements.

Popular topologies for transformerless inverters include H-bridge, half-bridge, and full-bridge configurations.
These topologies were developed to address specific needs such as reducing size and weight, improving efficiency, and minimizing cost.
H-bridge topology is commonly used in single-phase transformerless inverters due to its simplicity and low cost.
Half-bridge topology is suitable for higher power applications and offers better efficiency.
Full-bridge topology is used in three-phase transformerless inverters and provides improved power quality and fault tolerance.
Other topologies like push-pull and flyback are also used in specific applications.
These topologies were developed to overcome the limitations of traditional transformer-based inverters and meet the demands of modern power conversion systems.
