Traditional EDM power supplies convert the energy at low frequency, directly from the utility line and they are able to deal with a wide spectrum of output power. The EDM power supply must achieve high voltage to generate the spark and large current to maintain the ion column. To achieve this, large and heavy transformers and inductances are required. Resonant converters are desirable for power conversion...
This paper proposes a method which consists of a phase shift converter with a current doubler rectifier on the output side, the operating frequency of the phase shift converter being as high as 20-25 kHz (depending on the requirement of the application), ferrite core transformer is used instead of conventional one, which being bulky leads to very large amount of core loss. Unlike the conventional...
Nuclear power plants have Normal and Emergency power supply systems. Both the power supply systems are to be reliable for safe operation of the plant. Prototype Fast Breeder Reactor (PFBR) coming up at Kalpakkam is a single unit 500 MWe project. The normal power supply system consists of two Station Buses and two Unit Buses. The station buses are fed from grid through a Station Transformer (ST). The...
