Advanced optimized pulse patterns (OPPs) that account for the magnetic anisotropy of permanent magnet synchronous motors (PMSMs) have recently gained the attention of the automotive industry due to the improvements they offer in the current quality. However, these improvements can lead to torque quality degradation and an increased dc-link current ripple. To address this problem, a hybrid modulation scheme that combines isotropic and anisotropic OPPs is proposed in this paper to achieve the best overall performance over the whole range of operating points. To do so, as shown with the presented results, different OPPs are assessed and those with the best overall performance are selected.

Nowadays, the on-board battery charger is a high dominant trend in research. For the AC/DC stage, many topologies are proposed worldwide without having true benchmarks among these different structures. Conventional single switch buck-boost converters were utilized earlier in various applications. However, it could not meet the requirements of the on-board battery charger due to higher component stresses and low reliability in high-power applications. Thus, AC/DC four switches boost buck converters are desirable, in which the boost cascaded with buck is superior because of the primary benefit of having a continuous input current. Moreover, they are more reliable, highly efficient, and have a significant operating capability as buck or boost mode according to the battery state of charge. This paper will examine four different kinds of four switches boost buck by comparing their input current ripple and magnet design. Furthermore, the lowest input current ripple converter will be selected for modeling and validate it experimentally.

Real-time simulation is increasingly employed in the validation of power electronics and systems, showing great potential in terms of flexibility and efficiency. With it, electrical behaviors of power converters can be simulated with high accuracy. However, when evaluating the reliability of converters, the switching behaviors of power semiconductors should be simulated, which normally requires a rather high sampling rate and powerful computational capability of the hardware platforms, and such simulations usually take much time Therefore, an efficient approach is introduced in this article to evaluate the thermal performances of power devices. Compared to the prior-art methods, the required sampling rate is much lower, and the proposed approach is also simpler, as only the three-phase current is sampled. The junction temperatures can be simulated with high accuracy. Preliminary results have also validated the effectiveness of this approach.

Digital twins (DTs) are playing a vital role nowadays in the EV industry. Since their inception, DTs have contributed significantly to the research development process. PMSMs are, are widely used in electric vehicles (EVs) due to their simple structure, good heat radiation capability, and high efficiency. In this paper, the performance of an EV-PMSM control strategy is evaluated based on DT concept. General principles of DT technology were discussed. The performance control model of PMSM was derived. Field-oriented control (FOC) and direct torque control (DTC) strategies for EVPMSM were discussed and compared. The PMSM DT architecture including physical, virtual, and service unit (data exchange) was proposed. EV-PMSM DT primarily functioned to evaluate the motor control algorithm. The motor’s actual speed was compared to the estimated one by its DT. The obtained results showed the effectiveness of the proposed DT to estimate the motor speed which would be used to develop a speed estimator to optimize the motor control strategy.

The energy transition requires electrical alternatives for domestic heating. Heat pumps are the most common alternatives to gas boilers. However, heat pumps consume a significant amount of electrical power. We simulated an 18-node low voltage network with five buildings with six apartments each to evaluate the effect of deploying heat pumps as part of multi-carrier energy systems at the residential level. We also combined heat pumps with solar collectors and thermal energy storage to quantity whether a more complex system benefits the low-voltage network. Replacing the gas boilers for heat pumps in the majority of the buildings resulted in voltage drops below the limit of the standard EN50160. The voltage drops were significantly improved when we included solar collectors and thermal energy storage in the domestic heating system.

Power factor correction (PFC) rectifiers is an old topic of research, which is assuming extra applicability to alleviate power quality complications in modern power grids. In this background, this paper proposes a novel PFC rectifier, which has as core differentiating characteristics the bridgeless structure, the interleaved current control, the operation with three voltage levels, and the dual output voltage. The proposed PFC rectifier works as a boost voltage topology, but offering an asymmetrical split dc-link, which can be advantageous in many applications as an AC-DC front-end converter. For all power range, the proposed PFC rectifier ensures a sinusoidal AC current in phase with the voltage, and controlled dc-link asymmetrical voltages. The paper outlines a broad clarification of the proposed topology, the operation principle, the employment of the control theory, and a set of computational results, attained with an AC voltage of 230 V - 50 Hz and a split DC-link voltage stabilized at 400 V. The proof of the topology and control of the proposed PFC rectifier is performed in steady-state, and also for sudden variations of the operation power.

In modern DC distribution networks both consumer and prosumer devices are interfaced to the grid via power converters equipped with suitable filtering circuitry to mitigate conducted electromagnetic interference (EMI), also referred to as conducted emissions (CE). However, the presence of asymmetries in the converter, such as the deviation of the component parameters from the designed ones and possible device failure, can significantly alter the input current and voltage waveforms while the device still works satisfactorily. This inevitably leads to an increase in the harmonic pollution in the power grid, being the EMI filters designed for acting on different waveforms. This paper investigates the effect that non-idealities of power switches have on the input current of an H-bridge inverter.

The growing popularity of Electric Vehicles (EVs) makes a growing need to build energy-efficient battery chargers to charge EVs batteries faster than before. Newly designed EVs have larger battery capacities and higher voltage ranges than their previous versions. Therefore, the recent onboard battery pack voltages are increased to 700-800 V ranges, to increase the battery capacities and reduce the charging time. On-Board Chargers (OBCs) are an essential part of plug-in battery EVs and hybrid vehicles. The most recent stage in the technological development of the available battery chargers is the two-stage approach. In this paper, the available two-stage ac-dc approach and single-stage matrix converter are compared comprehensively in terms of size, efficiency, and applicability to see which approach is more efficient. Finally, both of the structures are simulated in PSIM software with 12 kW output power, 800 V battery voltage, 100 kHz high switching frequency, and three-phase 50 Hz and 230 V grid to validate the theoretical analysis.

The paper presents a method for derivation of the minimum split DC link capacitance in three-phase three-level DC-AC converters operating with unity power factor with neither active balancing circuits nor AC zero sequence injection. It is shown that due to the fact that partial DC link voltages and AC-side phase voltages obtain extremum values at different instants, it is possible to reduce the minimum value of the former below maximum value of the latter while still ensuring correct operation of the power stage. Minimum attainable split DC link capacitance values are therefore obtained according to boundary case of tangency between the above-mentioned voltages. Analytical derivations are accurately verified by simulations and experiments, demonstrating close agreement.
