Abstract:

This project proposes a new hybrid voltage divider DC-DC converter that utilizes switching capacitors and inductors to produce zero voltage switching (ZVS) at the turn on state of its switches. By achieving ZVS, the switching losses are significantly reduced; thus, increasing the overall efficiency of the converter at various loads. The goal for this thesis is to perform analysis of the operation of the converter, derive equations for sizing the main components, and demonstrate its functionality through computer simulation and hardware prototype. Results of the simulation and hardware testing

Abstract:

For many high-speed, high-performance circuits, purely differential inputs are needed. This project focuses on building high-speed voltage converters which can transfer a single-ended signal to a purely differential signal, or a differential input signal to a single-ended signal. Operational transconductance amplifier (OTAs) techniques are widely used in high-speed continuous-time integrated analog signal processing (ASP) circuits because resistors, inductors, integrators, buffers, multipliers and filters can be built by OT As and capacitors. Taking advantage of OT As, very-high-speed voltage

Abstract:

Active transient voltage compensator (ATVC) has been proposed to improve VR transient response at high slew rate load, which engages in transient periods operating in MHZ to inject high slew rate current in step up load and recovers energy in step down load. Main VR operates in low switching frequency mainly providing DC current. Parallel ATVC has largely reduced conduction and switching losses. Parallel ATVC also reduces the number of VR bulk capacitors. Combined linear and adaptive nonlinear control has been proposed to reduce delay times in the actual controller, which injects one nonlinear

High voltage power supply design presents unique requirements, combining safety, controllability, high performance, and high efficiencies. A new Resonant Self-Tracking Current-Fed Converter (RST-CFC) is investigated as a proof-of-concept of a high voltage power supply particularly for an X-ray system. These systems require fast voltage rise times and low ripple to yield a clear image.

Abstract:

DC-DC converters can be separated into two main groups: switching converters and linear regulators. Linear regulators such as Low Dropout Regulators (LDOs) are straightforward to implement and have a very stable output with low voltage ripple. However, the efficiency of an LDO can fluctuate greatly, as the power dissipation is a function of the device’s input and output. On the other hand, a switching regulator uses a switch to regulate energy levels. These types of regulators are more versatile when a larger change of voltage is needed, as efficiency is relatively stable across larger steps o

Very low voltage, high current output requirement have necessitated improvements in power supply's density and efficiency. Existing power conversion techniques cannot meet very stringent size and efficiency requirements.

Both cores and windings are integrated. Consequently, the power loss and the size of the integrated magnetic device are greatly reduced. Detailed analysis

For A/D converters in ultra-wideband (UWB) communication systems, the flash A/D type is commonly used because of its fast speed and simple architecture. However, the number of comparators in a flash A/D converter exponentially increases with an increase in resolution; therefore, an interpolating technique is proposed in this thesis to mitigate the exponential increase of comparators in a flash converter.

Abstract:

碩士<br>國立雲林科技大學<br>電子與資訊工程研究所<br>93<br>An improved CMOS voltage-to-current converter is presented. PMOS transistors are employed in the resistor-replacement and voltage-level shifting of the proposed converter to avoid the body effect. To accurately annihilate the non-linear voltage terms, a better modeling of the drain-to-source current of the MOS transistor operating in the linear region is essential and is adopted. Specifically the substrate-bias effect of the MOS transistor is treated more thoroughly in our design. Consequently, the non-linearity of the large-signal transresistance of the c

碩士<br>國立東華大學<br>電機工程學系<br>97<br>This paper proposes a novel interleaved flyback converter which is composed of two parallel-operated basic flyback converters in addition to an auxiliary inductor and two snubber circuits. This circuit is able to transfer higher power at a much higher efficiency than conventional flyback converters. There are two efficiency boosting features in this proposed circuit. First, both the active power switches are zero- voltage-switched and therefore the switching losses are reduced. Second, the reverse recovery losss on the rectifying diodes are reduced. This is beca

碩士<br>雲林科技大學<br>電機工程系碩士班<br>97<br>An interleaved DC/DC converter with less power switches is presented in this thesis. Two forward converter cells are connected in parallel and unite common power switches without using extra switching devices to achieve the features of interleaving and zero-voltage-switching (ZVS). Active-clamping circuit is adopted at the primary side of transformers to circulate the energy stored in magnetizing inductor and leakage inductor of transformers and reduce the switching losses and noises on power switches. In addition, the paralleling manner with interleaving tec

Abstract:

碩士<br>國立中山大學<br>電機工程學系研究所<br>100<br>The purpose of this thesis is to design and implement a linear quadratic optimal controller for a twin-buck converter with zero-voltage-transition (ZVT). The controller calculates duty ratio every cycle based on voltage and current feedback, as well as estimates the time instances when the synchronous rectification power switch current is zero. These time instances are crucial for ZVT operation. Via frequency modulation, the controller is designed to automatically regulate the output voltage to a desired value under load and voltage source variation. Simulat

碩士<br>國立臺北大學<br>電機工程學系<br>106<br>This paper propose a self-calibration capacitor to voltage converter. It used the external capacitor variation transfer to the corresponding time signal by the temperature and voltage insensitive capacitor to time converter. This time signal will be transferred to the corresponding digital signal by the time to digital converter. After the internal capacitor is calibrated by the digital control circuit, it is converted into the corresponding output voltage by the capacitor to voltage converter. The proposed temperature and voltage insensitive capacitor to volta
