“…This type of multilevel inverter has the advantages of being simpler and cheaper when compared with other topologies. Besides this, the voltage on the switching power semiconductors, is half of the DC-link voltage and the output voltage and current have reduced THD [6,7], with smaller passive filter requirements [7].…”

This paper presents a single-stage three-level Neutral Point Clamped (NPC) inverter for connection to the electrical power grid, with integrated Maximum Power Point Tracking (MPPT) algorithm to extract the maximum power available from solar photovoltaic (PV) panels. This single-stage topology is more compact than the traditional topology, it was chosen because with the proper control strategy. It is suitable to connect the PV panels to the power grid. The paper describes the design of a 5 kW NPC inverter for the interface of PV panels with the power grid, presenting the circuit parameters and the description of the control algorithms. A phase locked loop control is used to connect the inverter into the grid. Then, a proposed DC Link voltage control to regulate the input voltage of the inverter. Although an MPPT algorithm was used to optimize the energy extraction and the system efficiency. Inverter Output Current control to produce an output current (current injected in the power grid) with low Total Harmonic Distortion (THD) implemented in a DSP. Simulation and experimental results verify the correct operation of the proposed system, even with fluctuations in the solar radiation.

“…The configurations of the single-phase multi-level inverter (SPMLI) and the single-phase H-bridge inverter (SPHBI) as well as the zero-voltage-switching H-bridge inverter (ZVSHBI) [3,[16][17][18] stand out because they only require one power supply compared to 5-level and 7-level inverters. Hence, they are appropriate to the application.…”

In this article, an advanced multiphase modular power drive prototype is developed for More Electric Aircraft (MEA). The proposed drive is designed to supply a multi-phase permanent magnet (PM) motor rating 120 kW with 24 slots and 11 pole pairs. The power converter of the drive system is based on Silicon Carbide Metal Oxide Semiconductor Field-Effect Transistor (SiC MOSFET) technology to operate at high voltage, high frequency and low reverse recovery current. Firstly, an experimental characterization test is performed for the selected SiC power module in harsh conditions to evaluate the switching energy losses. Secondly, a finite element thermal analysis based on Ansys-Icepak is accomplished to validate the selected cooling system for the power converter. Thirdly, a co-simulation model is developed using Matlab-Simulink and LTspice ® to evaluate the SiC power module impact on the performance of a multiphase drive system at different operating conditions. The results obtained show that the dynamic performance and efficiency of the power drive are significantly improved, which makes the proposed system an excellent candidate for future aircraft applications.

A multilevel inverter with a H-bridge clamp circuit is proposed for single-phase three-wire (1P3W) utility connected applications such as PV systems. The proposed inverter consists of two n-level inverters and a H-bridge clamp circuit. The proposed inverter requires only 12 controllable switches to obtain a 5-level output voltage though conventional multi-level converters with grounded neutral point of the DC-bus require 16 switches. The control strategy for the proposed circuit is also discussed in this paper. Moreover, a numerical parameter design method is established and then verified by experiments. Finally, the grid connected operation is presented by experimental results.
