Kinetic energy recovery on railway systems with feedback to the grid

Several proposals for using of power derived from regenerative braking in railway systems are available. We present an energy recovery system with feedback to the distribution grid based on a new converter topology; the dimensioning methodology of the system is based on real data intake and validated simulations. The new converter topology presented is based on the connection in cascade of a DC/DC elevator to a 3-phase inverter. This way, the system is freed from the limitations imposed by voltage fluctuations in the grid, allowing maximum recovery at minimum catenary´s voltages .
