There has been a growing adaptation of Variable Frequency Drives (VFD) for motor applications in all areas. Maximum Torque Per Ampere (MTPA) algorithms are common solutions that aim at achieving efficient operation of drives. This paper presents a novel offline MTPA trajectory generation scheme for an interior permanent magnet (IPM) motor drive. The proposed approach is based on calculating the minimum current possible for every load operating point by solving for polynomial roots of the torque expression in a closed form solution and considers non-linear saturation and cross-coupling properties of the IPM machine. The offline calculation and state logic have been implemented using a model-based design approach and key considerations have been made for efficient execution while minimizing computational resource requirements, thus expanding the deployment scope on a wide range of motor drives including cost sensitive applications. Experimental results obtained on a 3HP IPM motor demonstrate the effectiveness of the proposed scheme in achieving the MTPA control objective while maintaining control stability across all operating regions.

In the shipboard dc power system, dc bus voltage regulation through six-step operation of active front end (AFE) can conspicuously reduce converter loss, compared to PWM operation of AFE. Despite of the superior efficiency of the six-step operation, there have been few researches on the parallel operation of generators under the six-step operation. This paper proposes a framework for the parallel operation of permanent magnet generators (PMGs) under the six-step operation. In addition, a method for deriving the optimal dc bus voltage to minimize the total copper loss of paralleled PMGs with different parameters is proposed. The proposed optimal voltage regulation method is compared with methods only minimizing copper loss of a single PMG among the paralleled PMGs. By the optimal voltage regulation, the total copper loss can be reduced by up to 9.1 % and 29 %, in the simulation and the experiment, respectively.

Heavy-duty commercial electric vehicle (HDEV) charging stations, such as for freight trucks, must handle large peak power demands. Installing on-site energy storage can reduce the peak charging demand to avoid expensive and oversized utility-managed distribution equipment. To ensure optimal design of charging infrastructure, the trade-off between energy storage size and grid equipment ratings should be considered. This paper presents a bi-level multi-objective optimization framework to discover Pareto optimal designs, under the constraint of optimally sized power electronic converters and realistic power loss models. Under these considerations, the bi-level approach can greatly simplify the design process by breaking up charging station optimization into a system-level problem and multiple converter-level problems. Using industry-based HDEV arrival times and charging conditions, this bi-level approach is demonstrated for a 9port charging station. The resulting Pareto front showcases equipment sizing trade-offs that are necessary for informed charging infrastructure development decisions. The bi-level optimization Pareto front is compared the Pareto fronts of traditional, fixed efficiency converter models.

This paper presents a high performance Double Side Cooled (DSC) module based on trench Silicon Carbide (SiC) MOSFETs. The module thermal stack is optimized to reach a superior thermal performance and thereby, a high current density. The stray inductance of the module is minimized to allow the usage of a lower breakdown voltage semiconductor, allowing for further optimization of its conduction performance. The module is experimentally characterized, and compared with a Silicon- (Si) based Module to evaluate the efficiency benefits of SiC at the inverter level.

Multilevel voltage-balancing DC-DC converter (MVBDC) generally shows the advantages of simple structure and control, modularization, low electrical stress of switches, bidirectional energy flow, high power density and efficiency, which has good prospect in high-power and high-voltage DCDC application. However, with increasing voltage level of MVBDC, both the number of modules and the potential risk of fault increases. Therefore, the fault ride-through scheme and control strategy of MVBDC are proposed in this paper. By introducing the improved modules and redundant modules, the fault ride-through MVBDC (FRT-MVBDC) may achieve fault protection. Based on the analysis of topology and principle of FRT-MVBDC, the fault characteristics and fault ride-through strategy are discussed in detail. Finally, the simulation model of FRT-MVBDC is built to verify the fault ride-through performances with proposed control strategy.

This paper investigates the behavior of permanent magnet synchronous machines paired with field-oriented control under the effects of asymmetric delay in per-phase current measurement and position measurement delay effect. A mathematical model for field-oriented control with asymmetric 3-phase feedback delay was developed and used to obtain theoretical current step responses in the quadrature and direct axes, as well as obtain root locus results of the dynamic system. Step responses were also obtained in a simulated model using Simulink, and through experiments, while injecting varying levels of per-phase feedback delay. Increasing levels of asymmetric delay and increasing controller bandwidth, increased the systems’ sensitivity to instability. Delay in phase A and phase B were found to primarily affect responses in the q-axis and d-axis respectively. Unequal amounts of delay (asymmetric delay) on phase A and Phase B create substantial instability when compared with equal delay (symmetric delay). Asymmetric delay in current measurement also resulted in varying amplitudes in current response at varying rotor positions.

The electrification of transport is driven by the advances in power electronics. However, electrical systems driven by pulse width modulated (PWM) voltage waveforms experience increase in partial discharge (PD) due to the fast slew rate and switching frequency of power electronic converters (PECs). To address this dielectric challenge, our group has developed and reported an electret-based PD mitigation method that significantly reduces PD in PEC-driven applications. In this study, the electret-based PD mitigation approach is used to reduce PD caused by sinusoidal PWM (SPWM) voltage waveform. PD measurements are conducted without and with the incorporation of electret films that are fabricated via the triode corona charging method. The proposed electret-based solution to PD is expected to secure the dielectric integrity of the power-electronics-driven electrification of transport.

Electric machines for electric aircraft propulsion applications must be designed to deliver high levels of propulsive power under low air pressure conditions with maximum power density. The combination of increased electric field stresses attributable to medium voltage excitation, reduced air pressure at high altitudes, and elevated switching speeds of wide-bandgap power semiconductor switches raise the risk of partial discharge (PD) and insulation breakdown in the machine windings. This paper presents an analytical approach for predicting the inter-turn voltage distribution inside a machine winding based on distributed high-frequency turn models. This technique makes it possible to predict the localized peak turn-to-turn and turn-to-ground voltage stresses in every part of the winding. Analysis of the concentrated stator windings of a 1 MW surface PM machine excited by a SiC-based inverter shows that the peak turn-to-turn and turn-to-ground voltage values can exceed their steady-state peak values by as much as 100% during switching transients, significantly increasing the peak electric field stresses that must be accommodated when designing the winding insulation system.

With the ever increasing power demand for next generation aircraft, hybrid propulsion and more electrical systems, fault detection and protection are crucial to flight safety and reliable operations, especially for DC distribution network. Solid State Circuit Breakers (SSCB) using state of the art (SOA) wide bandgap (WBG) semiconductor devices are potential candidates to meet the fast action, high power density and high efficiency requirements for aerospace electrical systems. The objective of this paper is to introduce test methods to evaluate the operation and performance of these fast-acting protection devices. A literature review of the current SSCB technology is included in the introduction, followed by the design phase test criteria. Test circuits and experimental setup for both the dynamic breaking and steady state efficiency evaluations are described in detailed. Fault current interruption capability and to verify efficiency at nominal operating conditions of a medium voltage DC (MVDC) SSCB were demonstrated and verified through the test results.
