The harmonic currents generated by the modern power supply equipment cause power system heating and also add to user power bills. Personal computers are the major equipments which use the modern power supply ie switched mode power supply (SMPS).These SMPS draw non-sinusoidal currents from the supply which results in generation of harmonics. Power quality of the distribution network is been dist...

In the high power converters such as three-phase inverters is recommended to operate at low frequencies, due to the switching losses. In addition, modeling errors and non linear loads with unmodeled dynamics frequently degrade the controllers performance resulting in a poor transient response and instability. This paper presents a robust model reference adaptive controller (RMRAC) for three-pha...

The article discusses a methodology that allows for an accurate calculation of the parameters electrical equipment from point view optimizing power supply system. Taking into account characteristics transients processes makes it possible to select in maximum load modes. Modeling flows caused by changes consumers is carried out on example calculating circuit five junctions. It shown change direc...

This application note, which is the first of a two-part series, explains the basics of different SMPS topologies. Applications of different topologies and their pros and cons are also discussed in detail. This application note will guide the user to select an appropriate topology for a given application, while providing useful information regarding selection of electrical and electronic compone...
