Metodologia de projeto de filtros de segunda ordem para inversores de tensão com modulação PWM digital

Abstract: KEYWORDS:Voltage-source inverters, digital PWM, filter design procedure. This paper presents a systematized methodology of secondorder output filter for inverters that synthesize sinusoidal voltage waveforms through digital pulse-width modulation (PWM). The objective of this methodology is to determine the largest corner frequency of the filter that ensure the specification of the maximum total harmonic distortion (THD) admissible in the output voltages of the PWM inverter, for linear and non-linear loads. The… Show more

“…The three-phase voltage source inverter is widely used as power converter in many kind of applications and exist in literature several studies (Michels et al, 2005;Gabe et al, 2009). Although this kind of converter has a mature technology and robustness, the presence of a large electrolytic capacitor in the dc link causes a high-distorted input current with THD that can be over 140% as well as increases the costs.…”
