This paper describes the setup of a direct current to direct current (DC-DC) converter simulation using Matlab / Simulink's SimPowerSystems (SPS). The simulation is set up to focus on full drive cycle simulation to be able to visualize the effects of a control strategy on a drive cycle over time. The aim of these simulations is to compare the effects of different control strategies and to introduce a modular control strategy. A modular control strategy is proposed and tested and the effects of the control strategies are described and discussed. The load factor of the battery current is calculated to look for improvements in smoothness.
