In order to reduce the switching transitions of the power devices, only optimal transitions between consecutive voltage levels are used.. Selection of the optimal transition sequence is performed by evaluating a cost function. Article Title: Elimination of Low-Frequency Ripples and Regulation of Neutral-Point Voltage in Stacked Multicell Converters Article Snippet: This paper introduces a modulation method for the stacked multicell converters (SMCs).. The proposed method is implemented using phase-disposition pulse-width modulation and is capable of balancing and regulating the voltages of all the capacitors in the topology; i.e., the flying capacitors and the dc-link capacitors.. The proposed method is also able to eliminate the low-frequency voltage ripples that may appear in the neutral point (NP) of SMCs. Article Title: Voltage-Balancing Method for Stacked Multicell Converters Using Phase-Disposition PWM Article Snippet: This paper presents a voltage balancing method for stacked multicell converters (SMCs) based on phase disposition pulse-width modulation.. A cost function is evaluated to select the optimum state from a pool of redundant possible ones at each voltage level.. It is demonstrated that if sawtooth carriers are used for modulation instead of standard triangular ones, significant reduction in the switching frequency and the associated power losses of the power devices can be achieved without affecting the voltage balancing capability. Article Title: Power Quality Improvement Meeting Important Grid Codes Using Three-phase Five-level CHB Inverter with Improved Quarter and Half-Wave Symmetry Based Optimized SHM-PAM Article Snippet: Selective harmonic minimization-pulse amplitude modulation (SHM-PAM) scheme suppresses more number of selected voltage harmonic components of a predefined voltage waveform pattern for a wider range.. This work presents formulations of some improved five-level pulse patterns based on both quarter-wave symmetry (QWS) and half-wave symmetry (HWS) with a low number of switching instants using the optimized SHM-PAM scheme to meet the CIGRE WG36-05/EN 50160 and IEC 61000-3-6 gird codes.. The switching angles and normalized value of dc voltage sources are calculated by the recently reported dragonfly algorithm (DA) based optimization technique. |
