Generalized Multi-Carrier PWM Technique for Two-level Voltage Source Inverters. IEEE Transactions on Industrial Electronics, 70 (5), 4345-4355. https://doi.org/10.1109/TIE.2022.3190872.0278-00461557-9948https://hdl.handle.net/11441/174005Two-level voltage source inverters are the mainstream solution for many power applications. The conventional modulation method of such inverters is the single-carrier pulsewidth modulation (PWM) technique. In this article, the usage of a generalized PWM method with three independent carriers is analyzed. The carrier phase-displacement angles are evaluated in order to reduce the common-mode voltage (CMV) total harmonic distortion (THD), the dc-link capacitor current THD, and the phase currents THD. These targets are difficult to be met at the same time and a cost function is deployed in order to look for a suitable solution that develops a tradeoff between all the targets. The proposed method has been tested in a laboratory prototype demonstrating its superior performance.application/pdf11 p.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Harmonic analysismultilevel converterspulsewidth modulation (PWM)info:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1109/TIE.2022.3190872
