The Application of Power Electronic Converters to Ensure a Reliable Power Supply for Telecom Loads Connected to Distribution Networks

摘要

Information technologies are vitally dependent on extremely reliable sources of electric power. Even very short power interruptions and poor power quality are economically and socially increasingly unacceptable. These strict reliability requirements can be realized by applying novel power electronic systems in existing and new power grid configurations with or without embedded alternate and distributed energy sources. The flexibility and features provided by power electronic interfaces are illustrated in this paper. In addition to control of the real power, other functions can be incorporated into the design of the interface to provide services, such as reactive power, and resources associated with power quality. These include voltage sag compensation and harmonic filtering. The design of the power converter interfaces are discussed.
