This article proposes a simplified space vector pulse-width modulation (SVPWM) technique five-leg inverter with dual three-phase output. An idea to fed the dual tree-phase machine by the multiphase voltage source inverters (VSIs) is not new. Dual- and multi-motor drive systems are widely used in the industry applications. The most popular fields are: electric vehicles (EVs) and traction systems. Moreover, the specific characteristic of the dual-drive systems allow to use them in the paper and textile production process. Mostly these solutions utilize carrier-based PWM (CBPWM) techniques for the output voltage generation, however the SVPWM techniques might be also used for this purpose. The main idea of this paper is to simplify the modulation process and obtain the similar algorithms complexity and execution times for the space-vector and carrier-based PWM techniques. The proposed SVPWM strategy allows to decrease the number of calculations at the initial stage of the algorithm. The output voltages for both loads/motors can be generated independently, with different frequencies and amplitudes. Simulation results were obtained using the PLECS software package. The experimental investigation with RL load were conducted as well. The carried tests proved the effectiveness of the proposed modulation strategy. All results are shown in this paper.
