Space Vector Modulation for Multi-Source Inverters

Multi Source Inverters (MSI) as a magnetic-less approach for active control of Hybrid Energy Storage Systems (HESS) in Electric Vehicles (EVs) have been proposed lately. Using such technologies leads to more compact and more efficient HESS in EVs. In this paper, a novel Space Vector Modulation (SVM) technique is surveyed for a recently proposed modular MSI. This method is not limited to the proposed MSI and can be applied to any type of MSIs. Since SVM, in general, requires a heavy calculation burden, this method not only simplifies the mathematical computational steps, but also enhances the implementation speed, and lowers the hardware requirements. Different steps of the method are explained through theory and math. Simulation results are implemented on a recently proposed modular MSI for US06 driving cycle using vector speed control of the induction machines in Matlab/Simulink environment. Finally, the method is implemented on a 1 kW lab prototype of the MSI, which validates the theory and the simulations.
