Rezumat
In lucrare se prezinta sistemul de control si functiile echipamentului electronic SDMC-103 de tractiune al
troleibuzului cu motor de curent continuu. Este descrisa structura sistemului de control cu microcontroler AtMega128 al echipamentului de tractiune pentru un MCC de 110 kW si 550 V. Sunt aduse schemele si unele fragmente de program ale algoritmului de control general, cat si ale regimurilor de franarea/accelerare. Fiabilitatea si flexibilitatea sistemului de control este dovedita de utilizarea in trei state a sutelor de echipamente.

Abstract
This paper presents the control system of the SDMC-103 electronic eqiupmet for DC trolleybus traction. The
algorithm is presented for a specific case with a DC motor of 110 kW, 500 V and 1500 rpm. The implementation of the
algorithm is made writing it down in a C form and writing it into an Atmega128 microcontroller. The practical function
modes of the motor are introduced into the algorithm, and their adaptation into the diagram and program explained.
The reability and flexibility of the control system is proven on hundreds modules installed in three countries
