This paper describes different power quality problems in distribution systems and their solutions with power electronics based equipment. Shunt, hybrid and series active power filters are described showing their compensation characteristics and principles of operation. Different power circuits topologies and control scheme for each type of active power filter are analyzed. The compensation characteristics of each topology with the respective control scheme are proved by simulation and experimentally.

The ALOHA protocol was one of the oldest random access protocols, invented by Norm Abramson in 1969. The first wireless network, implementing packet switching over radio, used the pure ALOHA variation, have initially established in Hawaii.
