The aim of this paper is the analysis of voltage spikes arising at the gate-source terminals during the commutation of Silicon Carbide (SiC) MOSFET Power Devices. The voltage spikes are noticed in a half bridge configuration and they can be appreciated when a SiC MOSFET is in off state while its complementary is PWM commutated. The influence of the device technology and its packaging on these transient overvoltages has been properly modeled including internal device and board parasitics. Moreover, wide experimental tests campaign have been performed highlighting pros and cons of different device packages.

For flyback converters with long cables attached, radiated common mode (CM) current is the dominant radiation source. Radiated CM current is caused by the CM voltage driving the CM noise propagation loop including the converter and the antenna. This paper proposes a radiated CM current model to quantify the relationship between the CM voltages, impedance and currents. It is discovered that the significant impact from the transformer on radiated CM current is primarily from the CM voltage transformation. To characterize the CM voltage transformation, a transformer CM model extraction method is proposed. Based on the model, for radiated CM current reduction, this paper reviews transformer structures and proposes an interwinding capacitive coupling minimized coaxial shielding technique. And this paper also studies on the EMI filter design for radiated CM current reduction. The proposed modeling and reduction techniques are verified through experiments performed on a flyback converter with cables attached.

Single-phase grid voltage information such as phase-angle, frequency, and amplitude are crucial for synchronization and control of grid connected power electronic converters. In this paper, a new single-phase filtering technique based on multiple delayed signal cancellation (MDSC) is proposed to extract both in-phase and quadrature components of the selected harmonic component of the grid voltage signal. This MDSC technique provides the flexibility to configure the undesired harmonics and hence the delay time introduced by the operator can be reduced in comparison with existing techniques. The proposed MDSC filter can be applied to the enhanced PLL (EPLL) for accurate estimations of grid voltage information. To validate the effectiveness of the proposed method, experiments are conducted for comparing studies of the proposed MDSC-EPLL with the EPLL and the cascaded delayed signal cancellation (CDSC)-EPLL under various grid voltage disturbances.

For LCL-type grid-connected converter, the grid current control interacts with phase-locked loop (PLL) under weak grid, via point of common coupling (PCC) voltage. And PLL disturbance has negative effect on the grid current control. Thus, the grid current control renders undesired performance, even instability. To mitigate this problem, a simple small-signal disturbance compensation control method is proposed for three-phase LCL-type grid-connected converter. Under the proposed method, the negative small-signal disturbance effect of PLL dynamic on the grid current control can be reduced under weak grid, without changing the PLL parameters and structure. The current control performance and its robustness to the grid impedance changes are significantly improved. Moreover, the method is not influenced by the circuit parameters variation. Finally, the proposed method is validated by experiment.

This paper proposes an improved topology of unified power flow controller (UPFC) based on nine-arm modular multilevel converter which could realize the same function as conventional UPFC composed of two back-to-back modular multilevel converters (MMCs). The proposed improved UPFC topology based on nine-arm MMC (9AMMC-UPFC) could offer significant advantages, that the number of required submodules and arm inductors could be reduced by 25% and 50%, respectively over the traditional UPFC based on MMCs. Therefore, the system volume and cost could be drastically reduced. The structure and operation principle of proposed 9AMMC-UPFC are firstly illustrated in this paper. Next, phase-shifted carrier-based PWM technique including capacitor voltage balancing control is briefly described for the operation of proposed 9AMMC-UPFC. Then, in order to suppress the exclusive odd-order harmonics in circulating currents of proposed 9AMMC-UPFC, circulating current suppression control method is put forward. Finally, the performance of the proposed 9AMMC-UPFC are evaluated by the simulation and experiment results.

Silicon-carbide (SiC) MOSFETs are enabling electrical vehicle motor drives to meet the demands of higher power density, efficiency, and lower system cost. Hence, this paper seeks to explore the benefits that a gate-driver-level intelligence can contribute to SiC-based power inverters. The intelligence is brought by PCB-embedded Rogowski switch-current sensors (RSCS) integrated on the gate driver of a 1.2 kV, 300 A SiC MOSFET half-bridge module. They collect two MOSFET switch currents in a manner of high magnitude, high bandwidth, and solid signal isolation. The switch-current signals are used for short-circuit detection under various fault impedances, as well as for phase-current reconstruction by subtracting one switch current from another. The fundamentals and noise-immunity design of the gate driver containing the RSCS are presented in the paper and can be applied to any half-bridge power module. A three-phase inverter prototype has been built and operated in continuous PWM mode. On this setup, the performance and limitations of the short-circuit detection and phase-current reconstruction are experimentally validated by comparing with commercial current probes and Hall sensors.

This paper presents a new LED grow light structure based on a multi-output AC/DC converter with an embedded light detector and the control systems. The proposed multi-output AC/DC converter uses the primary side as well as secondary side control in order to regulate the light intensity and the light spectrum of the grow light. In addition, a light detector is embedded in the LED grow light to continuously feedback various parameters to the control system. The power circuit of the proposed AC/DC converter is based on a single-stage power circuit topology, which combines a bridge-less Power Factor Correction (PFC) topology and a resonant converter with multiple outputs. The control system of the AC/DC converter ensures the optimal production of light intensity and light spectrum in order to optimize the plant growth. Simulation and experimental results from a 600-watt LED grow light prototype verifies the feasibility of the proposed circuitry and demonstrate its superior performance.

The future power grid will involve increasing numbers of power converters while growing the complexity of the power systems. The future of the power converters is driven by developments in the wide-bandgap semiconductor devices. In this paper, a 50-kW string photovoltaic (PV) inverter designed and developed using all silicon carbide (SiC) semiconductor devices is presented. The inverter design includes an additively manufactured power block, symmetrical Y-core inductors for the ac-side filter, and advanced inverter controls for grid support functionality. This inverter uses the conventional three-phase voltage source inverter topology and optimizes the design for SiC-based devices. The paper includes details on power module design, heatsink optimization, symmetrical Y-core filter inductor design, inverter thermal design, and further experimental validation of the inverter performance. In addition to presenting the quantification of inverter efficiency and quality of the output, the paper presents the validation of advanced grid-support functions required by the IEEE 1547 standards for the interconnection of distributed energy resources.
