Hybrid SHM-SHE Modulation Technique for a Four-Leg NPC Inverter With DC Capacitor Self-Voltage Balancing
This article has been accepted for publication in a future issue of this journal, but has not been fully edited. Content may change prior to final publication. Abstract—In this paper, SHM (Selective Harmonic Mitigation) and SHE (Selective Harmonic Elimination) modulation techniques have been combined to produce appropriate pulses for four-leg three-level NPC (Neutral Point Clamped) inverter. In...
متن کاملPower Quality Analysis for Modular Structured Multilevel Inverter with Bipolar Variable Amplitude Multicarrier Pulse Width Modulation Techniques
MultiLevel Inverter (MLI) is used in applications that need high voltage and high current especially for Flexible AC Transmission System (FACTS) controllers. The topologies of multilevel inverter have several advantages such as lower Total Harmonic Distortion (THD), lower ElectroMagnetic Interference (EMI) generation and high output voltage. The main feature of Modular Structured Multilevel Inv...
متن کاملBuck – Boost Voltage / Current Source Inverter with Space Vector Pulse width Amplitude Modulation
This paper proposes a space vector pulse width amplitude modulation (SVPWAM) method for a buck–boost voltage/current source inverter. For a voltage source inverter, the switching loss is reduced by 87%, compared to a conventional sinusoidal pulse width modulation (SPWM) method. For a current source inverter, the switching loss is reduced by 60%. In both cases, the power density is increased by ...
متن کاملSinusoidal and Space Vector Pulse Width Modulation for Inverter
Inverters inherently have the property of controlling output frequency but the output voltage can’t be varied. Usually to vary output voltage we have to vary supply voltage which is not always possible for this reason PWM techniques gained momentum. Basic aim of PWM technique is to control output voltage and harmonic reduction. Pulse-width modulation (PWM), or pulseduration modulation (PDM), is...
متن کاملImproved Pulse –Width Modulation Strategies for Voltage Source Inverter
Abstract: The power electronics are gaining more popularity because of their user friendly behavior. Here the recently proposed improved PWM strategies are compared and the performances in the field of harmonic reduction are traced out. The strategies one prior to other helps in reducing the harmonics and gives the topology a major breakthrough in the field of voltage source inverters. The diod...
