Manganese-substituted nickel–zinc ferrites have been investigated as power core materials for applications in switched-mode-power supplies. High frequency operation of these power supplies requires high performance cores with low power losses. The main contributors to the power loss are eddy current loss, hysteresis loss and residual loss. The ferrites have been synthesized by the citrate precursor technique and their electromagnetic properties such as resistivity, permeability, saturation magnetization and Curie temperature studied. A power loss of 500 mW/cc could be obtained at a frequency of 500 kHz, flux density of 50 mT and temperature 100 °C.

Most of today's power converters such as three-phase variable-speed drives, uninterruptible power systems, welding converters, and telecom and server power supplies are based on voltage-source converters equipped with bulky DC-link electrolytic capacitors. To be able to handle full DC bus voltage, the DC bus capacitor is arranged as series-connected electrolytic capacitors rated at lower voltage. An electrolytic capacitor, however, is

Abstract-Medium and high power switch mode power supplies SMPS (> 500W) used in telecommunications stations are normally based on the full-bridge DC-DC converter with isolation transformer. According to the transistors states, the... more

The operation of front-end power converters can cause many undesirable effects in the Alternative Current (AC) power system. To prevent these undesirable effects, high-quality rectifiers, also called Power Factor Correctors (PFC) should be used. In this paper, power factor correction of switching mode power supply (SMPS) by using Neuro-Fuzzy (NF) controller is proposed. Average current control technique is used in
