[EN] The main purpose of this thesis was to analyse a new concept of hybrid electric vehicle drive system basing on existing examples of heavy mining machines. Recently hybrid drive systems are getting more and more important in the global market and that is why this study can be useful to the further development of those topologies. The study shows that the analysed scheme is stable, enables to drive the load with the power electronic converter at low speed and directly with the synchronous generator at high speed. The main advantage of using the inverter at stage of low power is that it works with smaller and cheaper devices, which makes the truck more ergonomic and economic. All graphics were made with the software Psim and represent the behaviour of the power, speed and torque levels of the machines. Because of the lack of some specific parameters of the machines, some data was estimated.
