Abstract:

This thesis presents the fundamental issues of the digital controlled DC/DC converter. A lot of challenges exist when you introduce the digital control technique into the control of the DC/DC converter, especially with regards to the voltage regulator module. One issue is the limit cycle oscillation problem caused by the quantization effect from the ADC and DPWM of the digital control chip. Another issue is the delay problem coming from the sample-hold effect. In this thesis, the modeling, analysis and design methodology for the constant frequency voltage-mode control is reviewed.

Abstract:

One of the fundamental characteristics of the microprocessor application is its property of dynamic load change. Although idle most of the time, it wakes up in nanoseconds to support sudden workload demands, which are becoming increasingly severe in today's multi-core processors with large core count. From the standpoint of its voltage regulator (VR) design, it must have very good efficiency at light loads, while also supporting a very fast transient response. Thus, the variable-frequency constant on-time current-mode (COTCM) control scheme is widely used in the VRs, as it can automatically re

Abstract:

Two novel clamped-mode resonant converters are analyzed. These clamped-mode converters operate at a constant frequency while retaining many desired features of conventional resonant converters such as fast responses, zero-voltage turn-on or zero-current turn-off, and low EMI levels, etc. The converters are able to regulate the output from no load to full load and are particularly suitable for off-line, high-power applications. To provide insights to the operations and derive design guidelines for the clamped-mode resonant converters, a complete dc characterization of both the clamped-mode ser

Abstract:

Peak current mode control is a popular method of SMPS control due the inherent cycle-by- cycle current limiting, feed-forward control and current sharing ability it provides. However, the subharmonic oscillations which plague peak current mode control must be removed using slope compensation. Until the work presented in this thesis, there have been no true digital implementations of peak current mode control due to the difficulties associated with implementing a digital form of slope compensation. This thesis introduces a complete digital peak current mode converter which uses a novel method o

Due to unique characteristics, current-mode control architectures with different implementation approaches have been widely used in power converter design to achieve current sharing, AVP control, and light-load efficiency improvement. Therefore, an accurate model for current-mode control is indispensable to system design due to the existence of subharmonic oscillations.

Abstract-- Static power converters produce harmonics due to the nature of the conversion process. This paper will investigate the effect on the power factor of a sinusoidal and Fryze current reference on a PWM boost type rectifier. It has been shown in previous papers that a Fryze current ref is best. This paper will develop a mathematical model, based on the single sided Fourier expansion. Using this mathematical model it will be shown that even though a high harmonic content could be present in a Fryze controlled PWM boost type rectifier, the power factor has been optimally improved.

The thesis begins with a review of presently available analogue and digital control schemes for high frequency PWM converters. Advantages and disadvantages of each scheme are identified, to determine which features would be desirable in a new digital control scheme. An extensive examination of peak and average current mode control is undertaken, using state-space/sampled data modelling, to gain more detailed information on the properties of current mode control. On the basis of this information, a new digital current mode control scheme is put forward. This uses samples of the inductor current

Electromagnetic Interference (EMI) filters take up a more than 80 % of these power converters, the size of these filters can be reduced by pushing the switching frequency higher.

碩士<br>國立中央大學<br>電機工程研究所<br>99<br>In this changing rapidly era of electronic technology, the major demands of portable electronics are short, thin, and full functionalities. These sub-circuits of the portable electronics, which use batteries for power sources, need a stable supply voltage generating by power converters. These power converters must have low power consumption and high efficiency to extend the service time of portable electronics. Thus, a high efficiency current mode buck converter is presented in this thesis. The proposed buck converter uses current-mode controlling mechanism to

碩士<br>國立成功大學<br>電機工程學系碩博士班<br>97<br>An integrated DCM buck converter with peak-current mode control is presented in this thesis, and a systematic procedure including system level, circuit level and transistor level is introduced. Mathcad, SIMPLIS and HSPICE are used to simulated, respectively. The DC–DC converter is fabricated with a TSMC 0.35um CMOS technology and the chip area is 1.423 x 0.812 mm2. Experimental results show that this converter can operate 500kHz with supply voltage from 2.7 to 4.2 V, which is suitable for single-cell lithium-ion battery supply applications. The output voltag

碩士<br>亞東技術學院<br>資訊與通訊工程研究所<br>103<br>In recent years, the portable electronic products, such as smart phones, wearable device, and even SOC embedded system, etc. grow fast. To meet the needs of today market which is toward compact size and wireless transmission, it is anticipated to have a long working hours and standby time. Therefore requiring higher power conversion efficiency, fast transient response and stability of the power supply of the power converter is design issues. In this Thesis, a current-mode CMOS PWM control buck converter is implemented for above applications. The circuit str

Abstract:

碩士<br>國立臺灣大學<br>電機工程學研究所<br>101<br>In the past, the DC-DC converters used for computer power applications usually employ a constant-frequency variable-duty-cycle controller. This type of control, however, often causes low conversion efficiency under light-load conditions. In recent years, light-load efficiency has become a major design consideration for the reason that most of the electronic devices, whether for desk-top or hand-held applications, are most of the time operated under light-load conditions. Therefore, a new controller type, the constant-on-time controller, has been proposed and
