در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
Mitigation of Harmonics by Three-Phase Voltage Source PWM Rectifier
This paper is concerned with the design and simulation of a pulse width modulation (PWM) rectifier for three-phase Permanent Magnetic motor drive. Based on the mathematical model of PWM rectifier, the dual-close-loop engineering design with decoupled feed-forward control is applied in the 3-phase voltage source rectifier. The objective to be reached is to realize unity power factor at the input...
متن کاملOptimized she PWM Technique with Odd and Even Values Using GA for Three Phase Voltage Source Inverters
Selective Harmonic Elimination Pulse Width Modulation (SHEPWM) technique is one of the control techniques for inverters. It is mainly used for reducing the harmonic content in single phase and three phase inverters and to improve the power quality. The selection of switching angles for eliminating particular harmonic is difficult. The proposed method uses one of the soft computing techniques Ge...
متن کاملCurrent Regulator Instabilities on Parallel Voltage Source Inverters
Parallel inverters are often used to meet system power requirements beyond the capacity of the largest single structure. They have also been used to reduce harmonics, reduce PWM switching frequency and increase available output voltage or frequency. The type of parallel structure depends on the construction of the load motor, the most prevalent are dual three phase machines, split-phase machine...
متن کاملCompensation of Discontinuous Conduction in Three Phase Voltage Source PWM Inverters
Nowadays the increasing utilization of alternative energy sources demand power converters capable of delivering high quality energy to the low voltage grid. Good dead time compensation and linear operation are essential to keep low order harmonics at acceptable levels. High-current operating conditions are well handled by traditional methods, but low current behaviour and waveforms with multipl...
