Abstract

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 .
