Alternators are electro-mechanical types of equipment that can convert mechanical energy to electrical energy. These devices frequently are used in automo- tive industries. Therefore, it is important to test them before being assembled on the automobiles for increasing reliability. In this study, a transformer-less single-stage and single-switched alternating current-direct current converter structure is proposed in order to test the operation quality of the alternator. By using the proportional integral controller, a constant output voltage is provided at three different voltage levels. This is done since different test voltages are requested by the consumers as different alternators with different operational voltages are available in the industry. In addition, since no transformer is used in the proposed structure, the volume and production cost of the converter are appropriate. In this study, the proposed converter and the controller system are analyzed in Matlab/SIMULINK environment. In the analysis, it was seen that the proposed converter works with proper efficiency.
