“…The ANPC inverter is a member of half-bridge neutral point clamped inverter family, and it was introduced in [15], [16] as an alternative to neutral point clamped (NPC) inverter for improved loss balancing and better utilization of semiconductor chip areas in the inverter and is of widespread use, for instance, in renewable energy (e.g., wind, PV) and industrial drive applications [15]- [18]. The ANPC topology is selected for this study as it is shown in literature that NPC based topologies provide high efficiency with three level output voltage waveform with devices at 600 V blocking class for 230 V grid systems [19], [14].…”

Abstract-This paper presents the trade-off study of heat sink and output filter volume of a GaN HEMT based single phase inverter. The selected topology is three-level Active Neutral point Clamped (ANPC) inverter, and the main aim is to explore the benefits of the GaN HEMTs at 600 V blocking class on the system level efficiency, and power density under wide range of operating conditions. The paper starts by introducing the inverter topology, selected PWM scheme and followed by the device features, static and dynamic characterisation and continues with presenting and discussing the results of extensive experimental and analytical characterisation. After this, the impact of GaN HEMTs on inverter volume is discussed in terms of heat sink and output filter volume analysis under different switching frequency and heat sink temperature conditions. The calculation of heat sink volume and single stage LC output filter volume are presented with respect to experimental results of single phase prototype. The findings from static, dynamic characterisation and single phase prototype results clearly show that GaN HEMT has excellent switching performance under wide load current and heat sink temperature conditions. The high performance of the inverter lead to reduction of the combined total volume, including output filter and heat sink volume.

“…This paper calculates and compares the losses in the inverter for three different PWM strategies: SPWM, THIPWM e CB-SVPWM. The operation limits of the converter, critical cases are determined and analyzed as show in Table I [2]. Operating under these limits the losses in the inverter have their maximum imbalance , limiting the switching frequency and the phase current of the converter.…”

Abstract. This paper investigates the power losses in semiconductors for a three-phase, three level neutral point clamped (3L-NPC) inverter. Analytical expressions for the switching and conductor losses are derived. Three different modulation strategies are analyzed: sinusoidal modulation (SPWM); sine modulation with injection of the third harmonic (THIPWM); carrier based space vector modulation (CB-SVMPWM). Based on these strategies, the inverter losses are estimated through computational simulation under different operating conditions. The influence of these strategies on the losses is also analyzed.

Abstract- This paper presents a novel multilevel active-clamped converter topology, which is an extension to m levels of the three-level active neutral-point-clamped topology. The operating principle is established through the definition of a proper set of switching states and a transition strategy between adjacent switching states. The benefits of the proposed converter topology and control in comparison to alternative multilevel converter topologies are discussed. Simulation results of a simple dc-dc converter configuration are presented to illustrate the converter performance features.
