Abstract
The article deals with PSIM simulation results of
the regenerative energy storage process with
supercapacitors installed on the renewed Tatra T3A
tramcars. Bidirectional supercapacitor’s current
controller is connected to the filter capacitor of the
tram DC converter and in the tram braking mode
operates as a buck converter. The control scheme of
the buck converter is suggested with two PID control
loops: with filter capacitor voltage and supercapacitor
current feedback. The results of PSIM simulation of
tramcar braking process are given with and without
overhead current fluctuations. Simulation results show
the control system’s stability in both synchronous and
asynchronous operation modes of the tram DC
converter and supercapacitor’s current controller
