Nowadays, wind turbines based on a doubly fed induction generator (DFIG) are a commonly
used solution in the wind industry. The standard converter topology used in these systems is …

In this dissertation, several new approaches to interface the renewable energy resources to
a utility grid are explored. It is shown a DC collection grid is preferred due to its simplicity …

The power converter topologies of variable speed electric drives can be divided into two
groups. The first large group is based on the voltage source inverters, while the second one …
