Detail design of the AC regulator, logic and PWM pattern of the AC chopper is described and three-phase AC regulator using two single-phase AC choppers with V connected three-phase transformer configuration is proposed for three-phase application. The proposed three-phase system has advantages of system cost due to reduced switch number and gate driver circuits, size and weight because it uses a series compensated scheme. The proposed AC regulator has many advantages such as fast voltage control, high efficiency and simple control logic. Experimental results show that it can be used as step-down AC voltage regulator for power saving purpose very efficiently.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

The initial position detection technique provides initial position detection without using A/D converter, filter, current sensors, and hall sensors as shown in [Y.S. Lai et al., April 2003]. The PWM technique [Y.S. Lai et al., Oct. 2002] significantly reduces the conduction losses by invoking the concept of synchronous rectifier. The back-EMF detection technique offers noise-free back-EMF detection results for commutation control of inverter, while not using any filter and center-tap voltage.

Riaz, Ha Chan","doi":"10.1109/IECON.2003.1280674","DOIUrl":"https://doi.org/10.1109/IECON.2003.1280674","url":null,"abstract":"A handheld set implementation using a wireless VoIP protocol is an inexpensive and effective solution to cellular phones. Although network to network interface has already been implemented using VoIP, the bottle-neck for wireless network is usually at the wireless access interface. Extending the use of IP packet to the edge benefits companies with cost management and effectively raise its customer base. A VoIP implemented in a handheld phone will deliver a more robust solution of VoIP from user to end user interface. Implementation of a handheld wireless VoIP handheld set needs new hardware. Functionality in wireless chipsets has been divided between MAC/DSP/RF layers. The medium access controller (MAC) layer serves as the media information interface and controller. The wireless VoIP custom chip in this design integrates those functionalities to implement the handheld wireless VoIP handset. The Physical layer includes the base-band signal processing functions and the RF front-end circuitry, provides the necessary filtering and variable gain, and signal converter functions. With the MAC and base-band DSP functions at the back-end of the physical layer having been fully digitized, these functions may be integrated onto a single digital chip. Vendors then provide the front-end physical layer functions, RF and analogue circuits on RF chips, usually incorporating minimal digital functionality while the back end of the functions can be implemented more efficiently using the DSP technology.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

Until recently, only resonant converters with 2 energy-storage elements have been studied and used for applications. However, some drawbacks of this class of converters can be overcome by the judicious augmentation of the resonant circuit. This paper presents the results of a study performed on two novel 4-element current-source resonant inverter circuits. These include analytical results on their steady-state characteristics (including input impedance, resonant frequency, input-output transfer function, component stresses, and efficiency). In addition, examples of design charts and experimental results are shown. They indicate that these resonant inverters have certain advantages over present ones.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

In particular, after a brief recall of two loss minimization control strategies (the \"search control\" and the \"loss-model control\"), both a modified dynamic model of the PMSM, which takes into account the iron losses, and a \"loss-model\" control strategy, are treated. Experimental tests on a specific PMSM drive employing the proposed loss minimization algorithm were performed aiming to validate the actual implementation. The main results of these tests confirm that the dynamic performances of the drive are maintained, and enhancement up to 3.5% of the efficiency can be reached in comparison to the PMSM drive equipped with a more traditional control strategy.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

The proposed method bases on the tracking algorithm of the resonant frequency. Therefore, the proposed method can keep unity output displacement factor at the load-impedance varying conditions. In order to control the output power, the proposed scheme uses pulse width modulation (PWM) method. Thus, since the proposed PWM scheme needs load-circulating operations, it can be adopted in the full-bridge inverter, but not in the conventional half-bridge inverters. In response to that, this paper also proposes a new half-bridge resonant inverter having load-circulating operation modes. In this paper, detailed switching schemes and control circuits of the proposed PWM method are described. Experimental results of the prototype experimental setup to verify the validity of the proposed method are presented and discussed.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

The voltage drop across the semiconductor devices is significant in comparison to the available dc-bus voltage and must be taken into account. Furthermore, in 42 V applications, in which batteries are utilized as the energy source, the dc-bus voltage extremely fluctuates due to the load-dependent behavior of batteries. Therefore, the battery behavior should be also regarded in the drive system model. This paper presents the modeling of a switched reluctance drive for 42 V application regarding behavior of the converter as well as the energy source. The entire switched reluctance drive system is modeled in a single simulation platform MATLAB/Simulink. The model accuracy is verified by the experimental results presented at the end of the paper.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.
