Emulating photovoltaic (PV) modules in a controllable lab environment to interface with power electronics hardware is challenging but vital as it enables more realistic experiments to be conducted in real-time. However, the emulation methods often require nonlinear PV modeling, which may have long computational times. Hence, an effective real-time emulation method should minimize the computation time while maintaining high accuracy. This work compares different PV emulation techniques to investigate the advantages and disadvantages of various methods for real-time hardware testing. First, a literature survey compares the type of PV model, interface used, controller, and real-time technique adopted to emulate a PV model’s current-voltage characteristics. Then, the PV model emulation methods are compared using a low-cost real-time emulator (RT Box 1), and computational cycle times are measured. The target application is to emulate a PV panel over various days and test the system control algorithm in real time for a PV microinverter with an integrated battery.

This paper focus on the stability issue of an inverter test system with a current source type motor emulator (CSTME). The CSTME imitates various motor operations with accuracy. However, the CSTME requires high current control bandwidth to prevent interference between the current controls of both the inverter under test (IUT) and the CSTME. This paper reveals the required current control bandwidth, which is to prevent interference between current controls, based on root locus analysis results. From the result of the stability analysis, the current controller of the CSTME requires 2.2 times higher bandwidth than IUT’s bandwidth. The stability limit of the root locus analysis agrees with the simulation of the time domain. In addition, the effect to the stability limit with time delay is also investigated. Then, the CSTME’s required current control bandwidth becomes more than 3.1 times of that of IUT. The validity of the analysis is verified by the simulation on the time domain.

Using ensemble learning (EL) for battery state of health estimation has become a research hotspot. Because the performance of a single estimator can get boosted, which is applicable in the field of the battery especially when the amount of aging data is insufficient. Traditional EL is to aggregate base models through averaging, which will introduce errors from poor base models. To fully use the estimation results from base models, a statical post-processing method is proposed in this paper. The EL algorithm is initially constructed by combining random sampling and training multiple extreme learning machines. Then the post-processing is performed by fitting the kernel probability distribution of all sub-outputs and determining the most likely estimate, i.e., the statistical mode. As for comparison, the performance of other aggregations using average, weighted average, and mode from a normal distribution are investigated. Finally, the effectiveness of the proposed method is verified by conducting aging experiments on an NMC battery. The root-mean-squared error is as low as 0.2%, which is an approximate 80% improvement in accuracy over the traditional average-based method. The proposed method tackles the unstable estimation in learning with a small dataset, which is suitable for practical applications.

With the development and popularity of electric vehicles, the power level and power density of on-board chargers for EV charging system are constantly increasing, with the more complex status of operation. Recently, a new reliability testing method using power electronic converters to emulate the actual working conditions, which is called the mission profile emulation, has been proposed. However, this method is barely reported in the application of on-board chargers. Therefore, this paper aims to propose a novel MPE system for the testing of on-board chargers, where a power-electronics-based mission profile emulator is used to mimic the electrical characteristics of the lithium-ion battery pack. With the power electronics interface, this emulator allows plug-and-play tests for on-board chargers. Moreover, an extended series-parallel model and a small-signal linear AC impedance model of battery pack have been proposed. Simulations are realized in PLECS for comparison and verification.

Gallium nitride (GaN) high electron mobility transistor (HEMT) is used in various high frequency applications, due to its extremely fast switching speed and low conduction resistance. However, GaN HEMT has poor reverse conduction characteristics under the turn-off condition which causes a dead-time loss. Therefore, as the system switching frequency increases, the effect of the dead-time loss becomes significant. Prior research tried to optimize the dead-time to handle the loss, but these methods need complex mathematical models and real-time calculations according to the load current. To overcome these complex model and calculations, this paper proposes an active gate driver (AGD) to reduce the dead-time loss without any real-time calculation. The circuit design of the proposed AGD is described and the operation sequence is verified with experiment. And the proposed AGD is applied in GaN-based dual active bridge converter to prove the effectiveness of the proposed method. By using the proposed method, the experiment results show that the system efficiency is increased in all load condition.

A compact and low-profile high frequency (HF) power converter is essential for a magnetically resonant wireless power transfer (WPT) system suitable for a small-scale electric load such as IoT equipments and medical implantable devices. This paper presents a new prototype of a class E HF inverter/active rectifier-based WPT system, where the load power control achieves only in the receiver (Rx) side while maintaining zero voltage soft-switching (ZVS) on the transmitter (Tx) side with the fixed frequency and duty cycle. The modeling-based analysis and design of PWM-controlled Rx-side class-E rectifier are originally presented in accordance with load-independent ZVS in the Transmitter (Tx)-side class-E inverter. The effectiveness of the modeling and design of the class-E2 WPT system are verified by experiment of 1MHz-8W prototype, after whereby the load-independent ZVS performance of class-E inverter is demonstrated with the relevant steady-state characteristics.

This work proposes an approach to find an appropriate bandwidth of a first-order low pass filter (LPF) used in a DOBC. It is established that an observer in the DOBC can guarantee precise estimation if its bandwidth is set as high as possible in order to reject disturbances in a broad frequency range. On the other hand, there is an upper bandwidth limitation due to the system robustness and potential noises; hence, the bandwidth is required to set to be smaller than the limit. In this work, we propose a method of selecting proper bandwidth for the LPF in the DOBC. To show the effectiveness of the proposed method the experimental studies are carried out using the permanent magnet synchronous motor (PMSM)..

The initial defect or performance deviation of the produced lithium-ion battery can be easily identified, but identifying a cell with a potential problem is a challenging study. A potential defect affects the performance and safety of the cell in the process of using. The batteries are applying to the varying application field requiring high capacity and power performance, many numbers of cell are connected in series and parallel for the system needs, wherein the problem of individual cells directly affects the performance and stability of the system. In other words, it is very important to understand the behavior characteristics of a potential cell to ensure the performance reliability and stability of the battery system. This research understood the potential thermal runaway (TR) behavior characteristics of cell through a TR experiment with pouch cell, which was manufactured by reproducing potential cell failure, and derived characteristics to identify and isolate failure cell.

This paper presents how to implement non-inverting boost-buck converter to achieve near unity power factor application. The advantage of the proposed converter is that it has continuous currents at both input and output, and its gain can be adjusted to higher or lower than unity. Steady state operation of the converter is also described by using circuit simplification. Since its input current is continuous, it can be applied for power factor correction. This work shows how to make the input current to have the current from ac source close to sinusoidal waveform with the same phase. In order to achieve that, programmed PWM technique is used to control the switches in the converter. Computer simulation is also given to confirm the work.

This paper proposes a new approach for design of power electronics converters considering reliability and stability issues from a system level perspective. Conventional design approaches rely only the reliability of the overall system. However, a converter failure can also introduce stability issues, which in turn increase the risk of loss of load in power electronics-based power systems. This may be severe considering increasing failure rate due to aging of converters. In this paper, a modeling approach is proposed to link the reliability of the converter, stability, and risk of the system in order to design a converter to guarantee acceptable performance of the overall system. Simulations on a hybrid micro grid (HMG) illustrate that even though the stability issues increase the total risk of the system, optimal oversizing and redesigning of the critical components can reduce the risk of system and minimize the adverse impacts of the system stability.
