Controller tuning of voltage source converter (VSC), using voltage oriented control (VOC), has a significant impact on the system stability against disturbances. To this end, optimization algorithms are sought in order to achieve optimum dynamic performance. Such algorithms are normally applied to numerical simulators that are time-intensive, which hinders the design process. This paper proposes, for the first time, space mapping (SM) optimization algorithm for controller tuning in a grid-connected VSC system. SM is a surrogate-based optimizer that utilizes a ‘coarse’ model that is less accurate, yet extremely fast, to guide the optimization of the numerical, time-intensive ‘fine’ model. The development and employment of both models are presented in this study. Subsequently, the accuracy and efficiency of the SM algorithm are assessed by simulations. It is found that SM optimization algorithm can return a quasi-optimum solution in less than half the time taken by optimizing the fine model with adequate accuracy.

Voltage controlled inverters in ac systems are susceptible to damage if the controller is not properly initialized before startup. Since currents are not controlled explicitly, the voltage reference of the controller must be closely aligned with the point of common coupling voltage to prevent large current transients when power delivery begins. In this paper, we are focused on a particular control strategy called virtual oscillator control and propose a pre-synchronization method that guarantees graceful addition of units into an existing ac system. The proposed method is generalized and can be used to add oscillator-controlled inverters to a stiff grid or an islanded microgrid with other inverters. An equivalent circuit model of the pre-synchronization control is derived along with its dynamical properties, design guidelines are given, and experimental results are shown for a 1.5kW inverter.

This work presents a non-isolated hybrid topology targeting at 4:1 fixed ratio and high output current applications. This topology can be regarded as a compact integration of switched capacitor and autotransformer. The switched capacitors are soft charged and the two winding currents in the autotransformer are auto balanced. The transformer has quasi-DC current with negligible AC winding losses. To further study the performance of the transformer in the proposed circuit, the transformer is simulated with different current waveforms, and the results show that with quasi-DC current the winding losses do not increase with switching frequency, and they are at least two times lower than the losses generated from sinusoidal or square current. The proposed circuit is measured at 24V-6V step-down and up to 25A output current, achieving 96.7% peak efficiency. The same transformer is also tested in a full bridge testbench to compare winding losses with square current by measuring its temperature.

Synchronous electrostatic machines can deliver extremely low loss while holding rated torque, with recent direct drive demonstrations of 0.625 W/Nm holding torque. Until now, power electronics topologies have focused on the support of wide torque-speed operation of these machines, resulting in drive systems that are suboptimal for applications largely operating at stall. Leveraging the ability of these machines to support dc-voltages without saturation, bidirectional flyback DC-DC converters are arranged to form a compact three-phase differential-inverter from a line to line terminal perspective. The arrangement is analytically modelled and analyzed for the position and hold application. This topology provides large voltage-gain and reduced component count eliminating isolated gate drivers. Utilized in discontinuous conduction mode at high frequencies, the topology has reduced switching loss and reduced magnetic component sizes. These attributes provide a suitable roadmap for drive integration with the machine. For comparison to the analytical model the converter is simulated in PLECS and Vdq0 controller is utilized for charge-oriented control.

Wide-bandgap devices like silicon-carbide (SiC) MOSFETs and gallium nitride (GaN) HEMTs feature fast switching speed, low switching losses, and higher operating temperatures. However, with the high di/dt and dv/dt slew rates, even small stray inductances and capacitances can lead to greater overvoltages and ringing during switching transients. Therefore, commutation loop parasitics are critical for SiC and GaN implementations. This paper details the theoretical analysis, and finite element analysis (FEA) simulation comparisons of different 3D Printed Circuit Board (PCB) layout strategies developed for a 15 kW SiC three-phase matrix converter. A discussion and evaluation of device cooling methods to increase the power density of the converter is also included, where each method defines specific constraints on the PCB layout design. Specifically, the use of PCB thermal vias and embedded Aluminum Nitride (AlN) ceramic inserts is evaluated. The latter resulting in a total power loop inductance of 22.8 nH, including device parasitics, and a thermal resistance of 2.7 °C/W.

This paper presents a high power density LLC converter for Electric Vehicles (EVs) on-board low voltage DC-DC converter. The design specification imposes critical challenges on size and efficiency due to extremely high load current rating and wide input/output voltage range. The proposed design enables high switching frequency by using wide-band-gap (WBG) devices to significantly reduce the size of magnetic components and meet the power density requirement. A two-transformer configuration with series connected primary windings and parallel connected secondary windings is used to reduce the heavy I2R loss on the output side. The structures of parallel resonant inductor and transformers are carefully designed to reduce the fringing loss and AC conduction loss. A single phase 1.3kW LLC prototype with water cooling was built and experiment results verified the design considerations. The prototype achieved 3kW/L of power density and 97% peak efficiency. Full input voltage range from 250V to 430V and output voltage from 9V to 16V operation was verified with 96.5% efficiency achieved at nominal input and full load.

Rectifier topologies with reduced switch count can be employed in unidirectional power flow applications. These configurations have the advantages of less necessary driver circuits, since some power switches are replaced by diodes, and high reliability. Following this trend, the present work proposes a multilevel AC/DC converter composed of cascaded Totem-Pole Bridgeless cells with independent outputs. This structure is achieved by replacing one leg of switches of the traditional Full-Bridge cell by a diode leg. The operation analysis of the proposed topology is presented as well as simulation and experimental results to validate the theoretical approach.

An alloy gap is used in the place of air gap to mitigate the concentrated gap loss of nanocrystalline core of an LCL filter inductor in a high frequency converter. A finite element analysis (FEA) model has been developed to examine the performance of the proposed method and validated by experiments. Based on FEA results, the maximum eddy current loss density can be reduced by around 89% and 69% for two different winding placements, respectively. The total eddy current loss of the air-gapped inductor can be reduced by 29% and 27% with gap winding placement and side winding placement respectively by applying an alloy gap. As a result, the hotspot temperature can be reduced corresponding to a lower and more uniform loss distribution.

This paper describes the new design and control of on-board charger (OBC) and low-voltage dc-dc converter (LDC) integrated circuit for electric vehicles (Evs), which operates in three modes. That is, it charges the high-voltage battery (HVB) by grid to vehicle (G2V) operation, and it supplies the energy of HVB to grid by vehicle to grid (V2G) operation. Also, the low-voltage battery (LVB) is charged via HVB. In conventional integrated circuit, the additional control is required to deal with the wide range of voltages for HVB operations in all modes. Moreover, it has the limitation to increase the power efficiency. To solve these problems, the new integrated circuit with variable turns ratio of transformer is proposed. Its main operation and design considerations are firstly analyzed. Then, its performance is evaluated by simulation test, and it is compared with that of conventional integrated circuit.
