Família de retificadores multipulsos com topologias diferenciais de transformadores
(2011-02-01)
Multipulse rectifier topologies based on auto-connections or differential connections, are more and more applied as interface stages between the mains and power converters. These topologies are becoming increasingly ...
Optimization of multipulse converters with delta and Y-differential connections
(2009-12-01)
This work presents a study regarding the optimization of multipulse converters. A general expression for the connection (Δ or Y) for both 12 and 18-pulses is obtained and describes the output voltages on the secondary ...
