Digital pulse–width modulation control in power electronic circuits: theory and applications by angel vladimirov peterchev doctor of philosophy in engineering-electrical engineering and computer sciences university of california, berkeley professor seth r sanders, chair this thesis develops. Design of a grid connected photovoltaic power electronic converter thesis submitted to the faculty of electrical engineering department of universitet i f des pwm desired frequency of inverter pwm f sys clk clock frequency of dsp controller id d-axis current iq q-axis current ir irradiance lboost inductor in. The hysteresis controller induces large unpleasant audible noises because it needs to vary the switching frequency to maintain constant hysteresis current band in contract, the pwm controller is very quiet but difficult to design proper gains and control bandwidth due to the nonlinear nature of the srm in this thesis , the ac.
This method is based on the equivalent ac and dc circuits of a pwm clc-to~dc converter, which consist only of switches in the converter the ﬁrst part of the synthesis procedure is carried out without the participation of reactive elements for a given number of switches and other requirements, the ac topology and its control. A substantial part of the thesis concentrates on spectral analysis of random pwm waveforms, ie on the 23 voltage control of converters by pwm hybrid pulse-width modulation imc internal model control pdf probability density function psd power spectral density pwm pulse-width modulation pwr power. Switching operation this thesis focuses on controlling the speed of a dc motor using pwm technique (varying duty cycle of a square wave) and data acquisition systems virtual instrumentation is defined as the combination of measurement and control hardware and application software with industry-standard computer. Thesis modeling and design of a current mode control boost converter submitted by hong yao department of electrical and i would like to express my gratitude to my thesis committee members for their where d is the pwm duty cycle, or the ratio of the time sw1 is on, ton, to switch period.
The contribution of this thesis is the development of pwm in xilinx integrated system environment (ise) cad tools and the vhdl modeling is used in the design process of pwm pulse width modulation has been widely used in many applications especially in communication and control systems the paper develops high. A comparison between statcoms using pwm voltage control and hysteresis current control (hcc) yongan deng ' a thesis in the department of electrical and computer engineering presented in partial fulﬁllment of the requirements for the degree of master of applied science at concordia university montreal. Of three pulse-width-modulation (pwm) techniques by phuong hue tran a thesis submitted in partial fulfillment of the requirements for the degree of master of science in electrical various pwm strategies, control schemes, and realization techniques have been developed in the past two.
The research work presented in this thesis has been carried out during my phd study at the institute of control and industrial electronics, warsaw university of technology in the period 2004-2008 some part of the work was performed in cooperation with the electronics engineering department, university of seville,. The most important part of the sensorless control is the sample of the non-fed phase, so the software must synchronise the sample with the pwm signal and apply the necessary delays in order to avoid commutation spikes and execute a correct bemf measure the software must be able to control the motor.
This thesis proposes a complete modeling and control design methodology for a multifunctional single-phase bidirectional pwm converter in renewable energy systems there is a generic current loop for different modes of operation to ease the transition between different modes, including stand-alone.
