POWER ELECTRONICS

INTRODUCTION OF POWER ELECTRONICS :

Power Electronics refers to the process of controlling the flow of current and voltage and converting it to a form that is suitable for user loads. The most desirable power electronic system is one whose efficiency and reliability is 100%.

Take a look at the following block diagram. It shows the components of a Power Electronic system and how they are interlinked.

Power Electronics for Renewable Energy Systems

A power electronic system converts electrical energy from one form to another and ensures the following is achieved −

  • Maximum efficiency
  • Maximum reliability
  • Maximum availability
  • Minimum cost
  • Least weight
  • Small size

Applications of Power Electronics are classified into two types − Static Applications and Drive Applications.
