Improving the energy efficiency of the electric traction drive of a haul truck

The article is devoted to increasing energy efficiency of traction electric drive of haul truck, due to the use of energy efficient energy converter. Improvement of on-board energy converter, as a component of traction electric drive, is the most important task of increasing energy efficiency of an autonomous power supply of a haul truck. As an on-board power converter, traditional inverters are used on dump trucks, but their energy performance, namely efficiency and power factor can be significantly increased. This article provides information about multilevel inverters as a more energy-efficient replacement for traditional inverters. The use of these multilevel inverters can fundamentally change the energy consumption profile of dump trucks, leading to increased operating efficiency, i.e. energy savings and reduced environmental impact. A new fan-type multilevel inverter with improved topology, in comparison with traditional multilevel inverters, is proposed to improve the energy efficiency of a haul truck traction drive. Simulation modeling of the improved fan-type inverter topology is given. To demonstrate the positive effect of implementing the proposed topology, a comparative analysis of simulation results of a traditional bridge inverter, a five-level inverter with a neutral point, and an advanced fan-type inverter is given.
