NPC Multilevel Inverters Advanced Conversion Technology in APF

2018
Multilevel inverters are most familiar with power converter applications. In this current paper, we discussed another possibility for DC/AC energy conversion. Converters based on current source inverters (CSI) configuration, take an important role in active power filtering in term of harmonics compensate and increasing system efficiency.

A new Zero Voltage Switching three-level NPC inverter

2015 IEEE Applied Power Electronics Conference and Exposition (APEC), 2015
A novel Zero Voltage Switching (ZVS) three-level NPC inverter topology using a new ZVS Space Vector Modulation (SVM) scheme is proposed. A detailed operation analysis of ZVS three-level NPC inverter is given. The ZVS condition of the proposed ZVS inverter is derived and it can be achieved of all switches in the proposed inverter, which include both the

A Five-Level Boost NPC Inverter for Electric Vehicle

2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2020
This paper proposes a five-level boost Neutral Point Clamped (NPC) inverter feeding an induction motor drive for an electric vehicle. Two partly rated isolated DC-DC converters are implemented to maintain the voltage at the DC-bus of the inverter constant irrespective of the variation in battery terminal voltage.

A SVPWM control strategy for NPC three-level inverter

2011 IEEE Power Engineering and Automation Conference, 2011
Based on six divided regions of space vectors, the potential position of the reference voltage vectors is firstly determined according to the principle of rotating vector normalization method. Then the effective time of three synthesized vectors is calculated by the principle of the volt-second balance principle.

A NPC step-up inverter for thermo-electric generators

2015 International Conference on Clean Electrical Power (ICCEP), 2015
Among single stage, single phase, inverter configurations the Neutral Point Clamped topology is advantaged by its quiet rail switching mechanism, producing negligible common mode currents. However, it requires a double input voltage if compared with a classic full bridge inverter.

Fault tolerant SVM strategy for 3-level NPC inverter

Eighth International Multi-Conference on Systems, Signals & Devices, 2011
Assuring continuity operating of induction machine drives is crucial in the most of applications. Thanks to the number of their output voltages, and the extra degrees of freedom they offer, multilevel inverters have been adopted in many applications. In this paper, a new fault tolerant SVM strategy for induction machine drives based on a 3 level NPC ...

Base/gate drive suppression methods for NPC inverter legs

Proceedings of the 1996 IEEE IECON. 22nd International Conference on Industrial Electronics, Control, and Instrumentation, 2002
The base/gate drive suppression methods for the voltage source inverter leg are those which suppress base/gate drives of either of the two switching devices of the leg. These methods have the merits that they do not have the conventional dead time problem, raise the reliability of the leg, and others.

The Research and Simulation of Three-Level NPC Inverter

2016
Compared with the commonly used sine-wave pulse width modulation (SPWM) method, the space vector pulse width modulation (SVPWM) method has higher utilization rate of DC voltage and smaller output waveform distortion. This paper describes the basic principle and control algorithm of three-level SVPWM.
