A widely uniform and highly ambient robust DC magnetic field generator for precise motion sensors using inertial measurement units (IMUs) is newly proposed in this paper. Chronic problems such as low uniformity of magnetic field and geomagnetic disturbance of conventional Helmholtz, Merritt, Rubens, Lee-Whiting, and Tetra coils can be significantly mitigated by the proposed uniform DC magnetic field generator (UFG). Different from the previous air coils, the proposed UFG adopts a core-cage so that a strong and uniform DC magnetic field distribution can be generated inside the cage and that the UFG may be quite magnetically robust to ambient changes such as geomagnetic field and ferromagnetic objects. Design procedures for the UFG are fully established. Detailed designs of the UFG for magnetic field generation, enhancing uniformity, and geomagnetic cancellation are provided. Experiments for a prototype UFG of 30 cm × 30 cm × 30 cm size showed that the geomagnetic field inside the UFG was significantly attenuated by - 21 dB while the DC magnetic field uniformity (<; 10°) was achieved over 81 % of the total volume of 27,000 cm3.
本文提出了一种适用于惯性测量单元(imu)的高精度运动传感器的均匀度高、环境鲁棒性强的直流磁场发生器。提出的均匀直流磁场发生器(UFG)可以显著缓解传统亥姆霍兹、梅里特、鲁本斯、李-怀特和利乐线圈的磁场均匀性低和地磁干扰等长期问题。与以往的空气线圈不同，本文提出的UFG采用了芯笼，在芯笼内可以产生强而均匀的直流磁场分布，对于地磁场、铁磁物体等环境变化具有很强的磁鲁棒性。UFG的设计程序已经完全建立。给出了用于磁场产生、增强均匀性和地磁对消的UFG的详细设计。对尺寸为30 cm × 30 cm × 30 cm的UFG原型机进行的实验表明，UFG内部的地磁场衰减了- 21 dB，而直流磁场均匀性(<;10°)达到了27,000 cm3总容积的81%以上。

With the behavioral models of class E switching-mode circuits, we can simulate the steady state behaviors of original circuits efficiently. However, if the dynamical systems, which are equivalent to original circuits, include impulse modes, the behavioral models cannot be obtained. In this paper, we prove that the behavioral models are presented by using the Weierstrass canonical form, even if impulse modes happen. Since the proposed models are quite general, the procedures would be widely applied to behavioral modellings of various kinds of converters. We demonstrate effectiveness of the proposed models with some examples.

An LED constant-current driver was designed and presented by a pulse width modulation (PWM) dimming control circuit, a overheat protection circuit (OTP), a bandgap circuit, a current controlled oscillator and a temperature process compensation bandgap circuit (TPC). The PWM provides a duty cycle from 10% to 90%. In order to reduce the area of the layout, the TPC circuit use MOSFET to replace the traditional BJT and resister. The OTP circuit provides the negative temperature coefficient voltage to achieve the overheat protection mechanism. The propose design is implemented using TSMC 0.35 μm CMOS process and the temperature of the simulation environment ranges from 0 °C, to 150 °C. The post-layout-extracted simulation results reveal that the current channel provides 30 mA. The area of chip is 1.1 mm2 and power consumption is 0.314 mW justified by HSPICE simulations.

In this paper, a hybrid MMC-HVDC system which is composed of half-bridge submodules and full-bridge submodules is investigated to enable its capability during startup and severe dc fault conditions. Firstly, a novel two-stage startup control sequence is proposed considering the topological differences compared to the traditional half-bridge MMC-HVDC system. Then the ride-through strategies of the hybrid system under severe dc-side faults including single pole to ground fault and permanent pole to pole short circuit fault are proposed. Using the proposed schemes, under single pole fault, the dc power, dc current and the dc-link voltage are reduced to guarantee the maximum power transfer and protect the semiconductor devices and dc transmission line from over currents. Also, under pole to pole fault, the hybrid system can cut off the dc short circuit current by the dual converters of both sides and is ready for power recovery after fault cleared. The effectiveness of the proposed strategies are validated by a two-terminal reduced-size 21-level hybrid MMC-HVDC model on PSCAD/EMTDC.

Gallium Nitride (GaN) transistors have advantages in self-resonant reset forward converter (SRFC) at 1MHz for high reliability application. Main design challenges of the converter have been discussed in this paper, especially the selection of resonance parameters. Then, design of a SRFC working with constant frequency at 1MHz is presented in detail. Finally a 20W GaN based prototype is established in laboratory environment and experiment results verified that GaN transistor improvs the performance of the converter with high frequency and small size.

The proton exchange membrane fuel cell (PEMFC) is a kind of clean energy, and has a large advantage in the uninterrupted power supply (UPS) which is used in telecommunication base stations. The air-breathing fuel cells stack can simplify the whole system design and development. In this paper, the system configuration is introduced. Two 2.5kw air-breathing PEMFC are adopted to avoid the lower power operation of the PEMFC stack. Each stack has two cooling fans which also provide the enough reactive air, but another two fans are used as the redundancies. This design significantly improves the reliability of the system. The operating states of the system are drilled down. The control system framework is designed by using embedded-PCs. The results indicate that, the air breathing fuel cells UPS operate steadily, and have obvious advantage as emergency power in telecommunication base stations.

Bi-directional inductive power transfer (BD-IPT) systems are suitable for applications such as V2G where a bi-directional wireless interface between the electric vehicle (EV) and the utility grid has a number of advantages over a wired link. However, physical misalignment between the magnetic couplers of BD-IPT systems used in EVs are unavoidable and introduces variations in self-inductance, leakage inductance and mutual inductance. These variations invariably detune the compensation circuits, thus significantly increasing losses and affecting the power throughput. This paper proposes a hybrid BD-IPT system, which combines a parallel tuned inductor-capacitor-inductor (LCL) network and a series tuned capacitor-inductor (CL) compensation network to provide a constant power transfer over a wide range of spatial displacements. A mathematical is developed to investigate the behavior and the sensitivity to variation in parameters of the proposed hybrid BD-IPT system. The validity of the mathematical model has been verified using simulated results of a 3.3 kW hybrid BD-IPT system. Both theoretical and simulated results are presented to show that a constant power throughput and an improved efficiency can be achieved over a wide range of horizontal and vertical displacements.

In this paper, reduction of a switching-frequency ripple current flowing to a DC-link capacitor in a single-phase charger which consists of PFC and DC/DC converters is presented. In order to reduce the switching-frequency ripple current of the capacitor without any additional circuit, switching pattern of both converter circuits are discussed using triangular and saw-tooth carrier waveforms. The reduction effect of the switching-frequency ripple current is confirmed by analysis and experimental results, used in PFC and DC/DC converter.

This paper investigates the steady-state characteristics of 3-phase cage induction machines that use two series-connected and one isolated (TSCAOI) phase winding configuration to generate single phase electricity. In this configuration, one phase-winding excites the machine while the remaining two in series generate electricity at constant frequency under varying rotor speeds. The steady-state model, which is derived using symmetrical components, provides a clear insight into the behavior of the generator in TSCAOI configuration. Simulated steady state characteristics of a 3 kW, 4-pole generator are presented under various operating conditions to demonstrate the usefulness of the proposed model.
