Power-electronics-based mission profile emulation is becoming a popular solution to validate advanced features of power electronic converters. In order to improve the testing efficiency, the converter under test and the emulating converter are normally powered by the same power supply. Under this structure, there exists zero-sequence current path in the testing system. Thus, undesired current harmonics, instability, and extra losses may be introduced. Basically, these zero-sequence harmonics can be divided into low-order harmonics related to the fundamental frequency, and high-order ripples related to the switching frequency. The mechanisms and influences of the high-order ripples are focused on and analyzed in this paper. Sampling distortions will be induced, and thus, control errors will be triggered by certain control strategies. Simulations and experiments are provided to validate the analysis. Possible solutions to avoid the sampling distortions and control errors are also concluded and discussed.

A modular multilevel converter (MMC) based on single-delta bridge-cells is a promising multilevel converter for various high-voltage application. When the cluster voltage synthesis method based on the conventional triangular carrier wave of phase-shifted pulse width modulation (PSPWM) is applied, the quality of the cluster output voltage differs depending on the parity (which is the property of an integer of whether it is even or odd) of the number of cells per cluster. These differences of the output voltage quality are caused by the different effective level of cluster output voltage under the conventional triangular carrier based PSPWM. In other words, the total harmonic distortion (THD) of the cluster output voltage is indirectly related to the number of levels of the cluster output voltage. In this paper, the THD of the cluster output voltage is analyzed according to the relationship between the number of cells per cluster and the type of the carrier. In addition, the recommended carrier type for PSPWM is determined by whether the number of cells per cluster is odd or even. To demonstrate the analysis and comparison in this paper, a full-scale real-time simulation has been conducted.

The charging and discharging process of full-bridge submodules (FBSMs) and half-bridge submodules (HBSMs) in the hybrid modular multilevel converters (MMCs) under over-modulation conditions is different. With the modulation index increasing, SM capacitor voltage ripple will be greater, even destabilize the system. In order to keep balance and ensure the output voltage quality, an accurate and comprehensive analysis of capacitor voltage ripple is important. This paper provides a detailed analysis of capacitor voltage ripple characteristics segmentally, and derives the balanced operating boundary. On this basis, the relationship between capacitor voltage ripple, the modulation index and power factor angle are discussed, and two types of capacitor voltages ripple are proposed. Moreover, their maximum and minimum values are derived. Finally, simulation and experiments are implemented under different over-modulation conditions, and the influence of nearest level modulation (NLM) and phase disposition pulse-width modulation (PD-PWM) on capacitor voltage ripple is compared in experiments.

This paper proposes an online parameter estimation method for a series-series tuned inductive power transfer (SS-IPT) system. The reactance of the receiver coil and the equivalent load resistance are estimated using the proposed parameter observers. The transfer functions of the observers are derived, and the controller gains are selected to achieve a 500 Hz estimation bandwidth. A closed-loop mutual inductance observer with a 100 Hz estimation bandwidth is developed. The transfer function is derived based on a block diagram of the observer, and the controller gains are selected using the transfer function. The performances of the proposed observers are evaluated using the simulated results. The proposed observers can be applied to the high-bandwidth controllers and dynamic SS-IPT system.

In order to address the gap in comprehensive power flow (PF) analysis of multi-terminal medium-voltage direct current (MT-MVDC) distribution systems, this paper proposes a novel decoupled sequential PF algorithm based on Newton-Raphson (NR)/estimation-correction method. The presented algorithm is designed for an MT-MVDC distribution network and takes into account the PF equations of both generic ac/dc and dc/dc converters. The MVDC PF study is the main focus and the power losses of voltage source converters (VSCs) & dc/dc converters are considered for accurately deriving the dc powers at MVDC links. The proposed algorithm only requires to define a single dc power or current bus type, hence the bus type definition is simplified and the solution of multiple sub-Jacobian matrices can be avoided. A binary search method is employed to correct the estimated initial dc power/current values, which contributes to the searching time reduction. Although an external correction iteration is required in the dc PF derivation, the proposed algorithm still improves on the computation efficiency in comparison with coupled sequential ac/dc PF algorithms. An MT-MVDC distribution network incorporated into IEEE 14 bus system verifies the validity and efficiency of the proposed algorithm.

In this study, a gallium nitride (GaN) high electron mobility transistor (HEMT) combined with the operational amplifier was applied to develop a two-level linear regulator (TLLR). Using the TLLR, the operating current of the laser diode can be formed in the constant-current or pulse-width modulation mode to emit the continuous-wave or short-pulsed laser, respectively. When the operating current of the laser diode was operated at the high-frequency PWM, the parasitic elements on the GaN HEMT, laser diodes, print-circuit board (PCB), and power wires influence the rising-edge slope of the laser operating current. In accordance with the physical packages of the GaN HEMT and laser diode, their equivalent circuit model parameters were provided in this study; therefore, the TLLR simulation circuit with its parasitic element was established. The simulation and experiment waveforms can be obtained to confirm the developed TLLR.

In this article, a sigma converter for high-voltage bus converter is proposed. The sigma converter of input-series output-parallel consists of a LCLCL-DCX (DC Transformer) and a dual-transistor forward converter (DTFC). LCLCL-DCX transfers most of the energy, and it can deliver power with the fundamental component and the third harmonics, which makes it have a high efficiency. In this article, in order to further analyze the behavior of the converter and design control scheme, the small-signal model of proposed sigma converter is derived. And a voltage-mode control design is provided.

In the development process of power electronics system, a wide range of know-how is required for special purpose circuits such as main circuits, control circuits and gate drive circuits. The Universal Smart Power Module (USPM) has been proposed to solve these problems by converting the above circuits into one module to reduce the design cost and development time. To realize the USPM module, USPM controller was developed which has very high speed A/D converter and high specification SoC-FPGA chip, ultra high speed control calculation can be realized. In this paper, a new space vector PWM (SVPWM) method that improves the transient response and robustness by 10MHz sampling between carriers and compensating the output vector in real time. The output vector is recalculated in every 0.1us by using USPM controller, and the recalculation immediately reflected to the output vector, which improves the output characteristics of three phase inverter.

The electroluminescence effect of SiC MOSFET is correlated with parameters such as junction temperature and device current, providing a new approach for non-intrusive online device status sensing. However, existing discrete photodiode solutions have encountered bottlenecks with increasing monitoring parameters and decreasing sampling delays. This work proposes a SiC device status monitoring scheme based on the integrated miniature hyperspectral spectrometer. Convolutional smoothing and partial least squares regression are applied to the obtained hyperspectral data sets. The real-time online monitoring of junction temperature and device current is achieved under low signal-to-noise ratios where the device only emits light in the dead time. The synchronous detection errors for temperature and current are only 3.11°C and 0.81A, respectively.

The synchronous detection errors for temperature and current are only 3.11°C and 0.81A, respectively.","PeriodicalId":151155,"journal":{"name":"2023 11th International Conference on Power Electronics and ECCE Asia (ICPE 2023 - ECCE Asia)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122036091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
