Abstract Parallel power generation is natural and there should be a synergy between them. Due to the anonhomogeneous of transformers CTs and VTs and a load shedding system, the balanced act between self-power generation and national grid power system. The unit which is considered for case study has difficulty in synchronizing the national grid with the current oil circuit breakers and switch... Read More


Designing an Integrated Two-Phase Interleaved DC Convertor

Abstract We in this work, advocated an integrated two-phase interleaved dc convertor. Switching-mode amplifiers deliver large amount of energy to the transmitter’s power amplifier (PA) in the fourth generation (4G) long term evolution (LTE) wireless communication standard. The received results proved that tracking speed can be increased if two-phase switching-mode amplifier is used instead of single phase architecture. While experimentation it... Read More


The Performance of Buck DC-DC Converter for Gate Driver with Adaptive Dead Time

Abstract In the current work we studied the performance of the BUCK DC-DC converter with Zero Voltage Switching (ZVS). To test the object, we have advocated a simulation scheme of Gate Driver with Adaptive Dead Time. It enables the independence of ZVS from the current value at which the transistors are switched. We have simulated the influence on the switching losses... Read More
