High voltage low lossess 66KV transformer
Introduction The wind energy sector has seen tremendous growth and innovation over the past few decades. From modest beginnings in the 1990s, where wind turbines produced a mere 0.5 MW of power, today’s turbines are capable of generating over 10 MW. Despite these advancements, the voltage output of wind turbines remained at 33 kV for many years. However, a significant shift occurred in 2017 ...

Bridgeless single stage flyback converter–based computer power supply
A power factor corrected (PFC) bridgeless converter–based computer power supply (CPS) using multioutput flyback dc–dc converter is presented in discontinuous conduction mode (DCM) of operation. In place of the conventional diode bridge to convert ac voltage into uncontrolled dc voltage, two multioutput flyback converters are connected in anti–series across the single phase ac supply. The diode ...

Power losses from wind generated electricity in high voltage AC transmission: an analysis through simulation
In this paper, we have investigated different types of losses from wind generated electricity in high voltage AC (HVAC) transmission. Wind power generation is expensive in nature and it is thus necessary to know how much power is lost in the transmission. We have simulated an HVAC transmission system with a wind power generator in Simulink. We varied different components of the system namely wind ...

Analysis and design of a hybrid phase modulated converter
High–frequency transformer isolated DC–to–DC converters are widely used for power conversion in alternate energy and other applications. In such applications, it is important for the converter to operate with wide variations in input voltage. A hybrid phase modulated converter (HPMC) can achieve this with soft–switching characteristics. This paper presents the analysis of such a hybrid phase ...
