Performance Analysis and Comparison between Coarse WDM and Dense WDM
Published In: GJRE Part: F: Electrical & Electronic Volume: 13 Issue: 6
Although optical fiber communication is the best for transmitting data at a high rate, we are trying to push the data rate even higher. While the fiber channel may be capable of transmitting terabitper- second data rates, no existing single communication system can make complete use of this speed. Adding more and more fibers to the system as a method of increasing speed is uneconomical a...

Automatic Power Factor Improvement By Using Microcontroller
Published In: GJRE Part: F: Electrical & Electronic Volume: 13 Issue: 6
This paper represents the most effective automatic power factor improvement by using static capacitors which will be controlled by a Microcontroller with very low cost although many existing systems are present which are expensive and difficult to manufacture. In this study, many small rating capacitors are connected in parallel and a reference power factor is set as standard value into ...

Simulation of Load Variation Impacts on aDelta Modulated Inverter
Published In: GJRE Part: F: Electrical & Electronic Volume: 13 Issue: 6
A new concept of identifying the most preferable load to be connected in a single phase full bridge inverter undergoing delta modulation has been provided in this paper. The best load is selected depending on the minimized Total Harmonic Distortion (THD) that depicts the presence of little amount of harmonics at the output response of the inverter as it is undisputedly the case that harm...

Peak to Average Power Ratio Reduction of OFDM Signal by Combining Clipping with Discrete Cosine Transform-II
Published In: GJRE Part: F: Electrical & Electronic Volume: 13 Issue: 6
Orthogonal Frequency Division Multiplexing (OFDM) is a very attractive digital transmission method developed to meet the increasing demand for higher data rates in communications which can be used in both wired and wireless environments. OFDM consist of large number of independent subcarriers, as a result of which the amplitude of such a signal can have high peak values. High peak to ave...

Transient Stability Improvement of a Conventional Power System by Superconducting Fault Current Limiter
Published In: GJRE Part: F: Electrical & Electronic Volume: 13 Issue: 5
Occurrence of faults in a power system causes transients which decrease transient stability of that system. Superconducting fault current limiter (SFCL) is a promising solution to reduce and control this fault (short circuit current) which is inevitable to electric power systems due to growing interconnection of electrical power systems. In this paper, a simulated proof of the capability...

Discrete Time Averaging of Non-Ideal PWM DC-DC Converters Operating in DCM with Feedback
Published In: GJRE Part: F: Electrical & Electronic Volume: 13 Issue: 5
This paper presents a one-cycle-average (OCA) discrete-time model for PWM switched dc-dc converters operating in discontinuous conduction mode (DCM). The closed-loop system is considered in the presence of circuit parasitic. This model provides the exact OCA values of the output voltage and inductor current considering the conduction losses in the switching stage components. It also prov...

Development of Alternative Scenario for Ethiopia’s Electricity Sector by LEAP Software
Published In: GJRE Part: F: Electrical & Electronic Volume: 13 Issue: 4
Ethiopia, a country in Africa, is endowed with renewable energy sources such as hydro, solar and wind. These energy sources are economically exploitable and if electrical energy could be prouduced it could be surplus beyond the country’s demand. Exporting electrical energy, Ethiopia could earn more money without disturbing environment as it is a global warming issue now-...

Harmonics Reduction of a single Phase Half Bridge Inverter
Published In: GJRE Part: F: Electrical & Electronic Volume: 13 Issue: 4
This paper presents an approach to minimize the harmonics contained in the output of a single phase half bridge inverter. With a view to reducing harmonics an LC low pass filter is used which blocks the harmonics and undeniably passes almost sinusoidal output at the output terminal. An illustration of Fourier Transform has been provided in this paper in order to perceive both the fundame...
