This paper proposed an electronic ballast that uses an input current shaper to reduce the total harmonic distortion of the line input current, that only process a small part of the total power. Base on the minimum value of the conduction angle to satisfy the requirements of the IEC 61000-3-2 Class-C standard, the conduction loss of the ICS stage can be reduced. The input current shaper is achieved by using a bridge rectifier which acts as the Class-DE resonant rectifier. By using this topology the conduction angle of the diode can be increased to high enough for satisfy the IEC 61000-3-2 Class-C standard requirements. The proposed electronic ballast is designed for 36-W fluorescent lamp and operated at a line rms voltage of 220 V, a line frequency of 50 Hz with the switching frequency fixed at about 76 kHz. The experimental results show that the total harmonic distortion is 29.5%, the power factor is 0.96, a lamp-current crest factor is 1.42, and 95.2% efficiency at full power.

In this paper, we present the impact of mobility on our scheme called Location-based Routing with Adaptive Request Zone (LoRAReZ). In LoRAReZ, the size of expected zone and request zone are set adaptively based on the distance between the source node and destination node. We evaluate the impact of mobility on the performance of LoRAReZ in terms of packet delivery fraction, routing overhead, end-to-end delay, throughput and power consumption by comparing with those of the traditional Ad Hoc On-Demand Distance Vector (AODV) and Modified Ad Hoc On-Demand Distance Vector (MAODV). The results show that LoRAReZ can provide the better performance than those of AODV and MAODV.

This paper presents the use of particle swarm optimization (PSO) algorithm applied to the optimal design of the 4/2 switched reluctance motor (SRM). The main advantage of designing 4/2 SRM is the robust rotor structure for high speed unidirectional rotating applications such as the air conditioner's blower. In the designing process, the finite element method magnetics (FEMM) is also employed to analyze the designing SRM with its optimized parameters given by PSO. This PSO algorithm is efficient and flexible. The objective function is based on the ripple torque minimization with respect to rotor node position. The PSO algorithm is described and the preliminary FEMM simulation results will be given for verifying optimal rotor design by PSO algorithm. In the final paper, the complete FEMM simulation results with detailed analysis will be provided.

Enhancement of speech perception is a crucial aspect for cochlear implant (CI) technology. In a tonal language such as Thai, with segments (consonants and vowels) and supra-segments (tones), many crucial acoustic cues are to be taken into account for speech processing strategy, i.e., amplitude envelopes and temporal fine structure. This paper presents a new speech synthesis algorithm for CI, which combines an amplitude envelope extraction by the continuous interleaved sampling (CIS) strategy and a temporal fine structure extraction to construct carrier signals, and to use them for amplitude modulation based on each band's envelope. Synthesized initial phonemes using three different algorithms (Fu et al., Chen and Zhang, and the proposed algorithm) with six-band speech processor were evaluated by eight native Thais with normal hearing. The results show that the proposed algorithm produces the most significant improvement in speech intelligibility of the initial phonemes compared to the other algorithms. This suggests a possibility of using the proposed algorithm for CI devices, specifically designed for tonal languages such as Thai, to improve speech perception in CI patients.
语音感知的增强是人工耳蜗技术的一个重要方面。在像泰语这样的声调语言中，有音段(辅音和元音)和超音段(音调)，语音处理策略需要考虑许多关键的声学线索，即振幅包络和时间精细结构。本文提出了一种新的CI语音合成算法，该算法结合了连续交错采样(CIS)策略的幅度包络提取和时间精细结构提取来构造载波信号，并将其用于基于每个频带包络的幅度调制。采用三种不同的算法(Fu et al.， Chen and Zhang，以及所提出的算法)和六波段语音处理器对8名听力正常的泰国人进行合成初始音素的评价。结果表明，与其他算法相比，该算法对初始音素的语音可理解性有最显著的提高。这表明将所提出的算法用于CI设备的可能性，专门为声调语言(如泰语)设计，以改善CI患者的语音感知。

In this Paper, a new nonisolated single switch DC-DC converter with high voltage gain is proposed. The proposed converter introduced a hybrid switched capacitor technique for providing high voltage gain without high switch duty cycle. Also an auxiliary circuit has been applied to the proposed converter for providing soft switching condition. This circuit consists of two coupled inductor and one diode. Therefore converter switch is turned on under ZCS condition. The other advantages of the proposed converter are continuous input/output current, simple structure and PWM control. The principle of operation in continuous conduction mode (CCM) is analyzed. The proposed converter is simulated by PSPICE for confirming the results of theoretical analysis.

If a pulse frequency, a load resistance of an LLC current-resonant DC-DC converter are changed, the dynamic characteristics is varied greatly, that is, the LLC current-resonant DC-DC converter has non-linear characteristics. In many applications of DC-DC converters, loads cannot be specified in advance, and they will be changed suddenly from no loads to full loads. A DC-DC converter system used a conventional single controller cannot be adapted to change dynamics and it occurs large output voltage variation. In this paper, a robust digital controller for suppress the change of step response characteristics and variations of output voltages in the load sudden changes is proposed. Experimental studies using a micro-processor for the controller demonstrate that this type of digital controller is effective to suppress the variations.

Nowadays power electronics converter that uses for emulate electrical characteristic V-I curve of renewable dc power source are widely interested in research fields. This paper concerns with a photovoltaic (PV) array simulator using a classical dc/dc buck converter as power stage. The inductor current of the converter is used as control variable that is characterized by digital R-S-T controller, so the converter can emulate accurately the V-I curve, even under partial shading condition. Fundamental of controller design is presented with the technique of canceling discrete zero of plant. The details of PV array model are also investigated in order to prepare an appropriated current loop command signal. The design concept is realized by 330 Watts of prototype. Finally, the experimental results validate the proposed controller.

This paper proposes a new technique for designing a robust controller for an ACMC (Average Current Mode Control) buck converter. The proposed technique is based on the concept of 2DOF H∞ loop shaping control (2DOF HLS) which can be adopted to find the robust controller. However, the structure of the conventional robust controller is normally complicated with high order. This makes the difficulty in the implementation. The proposed technique can overcome this problem by using genetic algorithm (GA) to solve the structure specified 2DOF H∞ loop shaping control. Simulation results in the ACMC buck converter verify the effectiveness of the proposed controller.

In this paper, we investigate a path selection approach for wireless cooperative multihop communications with one source, one destination, and multiple intermediate relaying nodes, which are clustered linearly. Specifically, we adopt a cooperative maximum ratio combining (C-MRC) technique as a framework for the path selection approach, namely a C-MRC-based approach and a modified C-MRC-based approach. The performance evaluation is performed to measure a bit error rate (BER). Simulation results indicate that the proposed modified C-MRC-based approach is superior to the C-MRC-based approach, in which the SNR gain of 2 dB is observed at BER of 10-4.
