“…Power electronics have been utilized in a wide spectrum of applications, from doing a fly-back converter as grid interference topology in renewable energy [1], to designing low voltage DC systems in house appliances [2], aerospace applications [3], and most notably their integration into the traction chain of electric vehicles [4]. In order to achieve the latter, many research efforts have been dedicated to the development of new inverters such as Z-source inverters [5], T-type inverters and flying capacitor inverters [6,7] that are adapted to electric vehicles [8].…”

Electric vehicles have gained considerable attention recently due to the ever increasing demand for a viable alternative to the current fossil fuel-dependent modes of transportation. These automobiles are reliant on power electronics to generate the energy required for the motor. Traditional converters, namely the V-source (VS) and C-source (CS), are vulnerable to EMI noise, their main circuits cannot be interchangeable and they are either a boost or a buck converter. Therefore, their output voltage is strictly higher or lower than the input voltage. In an effort to negate these drawbacks, new inverters such as the Z-source were conceptualized. This work aims to study the applicability of the Z-source in the traction chain of an electric vehicle in order to feed a permanent magnet synchronous motor (PMSM). The latter is controlled with field oriented vector control reinforced with a backstepping technique in an attempt to ensure tracking ability and robustness. Energy management is also supported in this article in an effort to optimize the performance of the electric vehicle under different operating conditions. The simulation results show the effectiveness of the proposed system in enhancing the energy management of the vehicle, in addition to its simplicity which can facilitate an eventual implementation using a DSP or a Dspace platform.

“…Several new and hybrid MVSI topologies were proposed, most of which are modified and upgraded version of the conventional diode clamp (DiC), flying capacitor (FC), neutral point capacitor (NPC) and cascaded H-bridge (CHB) [7,9,10]. The converter topology and control strategy determine the type of filter needed as an interface to the grid [11].…”

“…the LCL filter with series resistors (LCL-S-R) and also the parallel resistor (LCL-P-R) connections. In some researches, it has been shown that the introduction of parallel damping resistors is better at suppressing the resonance effect and the THD component as compared to the series-configured one [4,9,13]. However, the majority of researchers fail to report the efficiency deterioration caused by incorporating the passive component into the system [38][39][40].…”

The high harmonic content produced by conventional converters has resulted in the increased system size and cost, due to the need for large-sized low-order harmonic passive filters and cooling system requirement. Given that, multilevel inverters and special modulation techniques were developed to suppress or eliminate the low-frequency harmonics and the left behind high-order ones are eliminated using a high-frequency small-sized filter. Hence, this paper designs and compares the total harmonic distortion (THD) and efficiency values of three set of filters, namely LCL filter, LCL with series and parallel resistance on a novel five-level multilevel voltage source inverter topology. The novelty lies with the proposed inverter, which, apart from using a single direct current source, it can extend it elimination capability beyond the normal five level using the concept of multiple switching per step and an optimised selective harmonic elimination pulse width modulation. The converter can eliminate eleven lower-order odd nontriplen harmonics, hence making the 37th harmonic at 1.85 kHz to be the first dominant harmonic. At 2-kW loading, two of the filters have THD below 5%, therefore satisfying the IEEE 519 standard. The parallel resistance damped filter (LCL-P-R) has less THD value but poor efficiency due to the resistance introduced into the circuit. The study was carried out using PSIM and MATLAB software.

This paper presents a comparative evaluation of multilevel DC link inverter of photovoltaic (PV) renewable energy system using either symmetrical or asymmetrical dc sources. The four units of dc source can have the same dc voltage level, ie 81.32 V, resulting in symmetrical dc sources. The asymmetrical dc sources consist of input dc voltages in binary sequence, 21.68 V, 43.37 V, 86.74 V and 173.48 V. The boost converters with maximum power point tracking (MPPT) capability which is regulated by perturb and observe (P&O) based control are connected between the PV panels and the four dc sources. The varying dc voltages from the PV panels are regulated to track the maximum power available regardless of the irradiance and temperature conditions. The symmetrical dc sources will facilitate the generation of 9 levels of staircase ac waveform rms of 230 V after the H-bridge inverter. Whereas, the asymmetrical dc sources are able to produce 31 levels of staircase ac waveform also with rated rms 230 V. Detailed analysis and comparison on the powers, ac output voltage, output current, total harmonic distortions, and MPPT achievement are described.
