This paper presents the main results and the details of methodology and control equations for a single phase 150kW pre-regulator rectifier for trolleybus system. The proposed structure allows Power Factor Correction (PFC) with low Total Harmonic Distortion (THD) in the current and in agreement with IEC 61000-3-4 international standards. The results presented in this paper come from a Research, Development and Innovation (R) project with AES Eletropaulo Metropolitana de São Paulo in partnership with Himalaia S.A. transportation company, and the main goal of this work is focused in encouraging the interest for the expansion of trolleybus paths from a platform with lower cost of installation and maintenance, without the DC substation necessity and looking for better quality life in the metropolitan areas of big cities. In this new proposal of power supply system modality, the trolleybus can be powered by both conventional direct current (DC) system and alternate current (AC) from the grid through a Scott transformer, keeping the two wires feeding system with a digital monitoring of the power supply types (DC or AC). Furthermore, the management and control systems are digitally implemented through a XC3S200 FPGA device. Finally, it should be informed that in the evolution of the proposed system, the authors are also working to eliminate the overhead lines using AC power stations specially developed for boarding/landing stations, removing the associated visual disadvantage of this modal, as well as reducing the system operation failures.
