This is part five of an eight-part series of a new Four quadrant dc chopper. The paper describes the parallel mode of the proposed Four Quadrants DC Chopper (FQDC) for a series motor. The mode is designed to overcome a disadvantage of dc series motors which is the speed reduction under load. First, it is studied via simulation using Matlab/Simulink model. Then the FQDC is experimentally tested on a 0.65kW series motor in a lab setup. Finally, a MATLAB/Simulink model is developed to apply the FQDC to a 35kW series motor that propels an electric car (EV). The results indicate that the proposed technique manages to prevent the speed drop of a dc series motor when loaded. This is evident when the EV is subjected to a hill climb.
