This paper presents the simulation of a Three Phase Five Level Cascaded H-bridge Multilevel Inverter. Third Harmonics Injection Pulse Width Modulation (THIPWM) technique was employed through s-function approach in SIMULINK environment to minimize the complexity of circuit design. The advantages of THIPWM are revealed in term of voltage and current THD reduction compared to Sinusoidal Pulse Width Modulation...
The paper discuss on the method and process of microgeneration of potential energy power produce by piezoelectric on vehicles. This microgeneration method of harvesting from the vibration of the car itself will be used in order to generate power and the piezoelectric expected capable of produce low voltage output. The piezoelectric generator will be used as the main component in the microgeneration...
This paper presents an alternative to improve the implementation of the torque and flux estimator for the Direct Torque Control (DTC) of induction motor drives in Field Programmable Gate Array (FPGA). The square root architecture is optimized to have low hardware resources utilization, by reducing the number of logic elements used, and subsequently contributing to reducing the power consumption. This...
This paper describes an analysis of modern controller, which uses output voltage as feedback to regulate its output voltage to a desired value without steady-state oscillations with the aid of Matlab® & Simulink® simulation software. This methodology is proposed to develop modern controller for application on boost DC-DC converter system with no parasitic components in the circuit. It is implemented...
Due to the high electricity demand and the decreasing of fossil fuel sources, most of the countries around the world goes to renewable energy such as wind, tidal and photovoltaic (PV) for electricity generation. Among these, the study of PV as an alternative source for electricity generation has gain wide attention. One of the important aspects that should be considered in PV application is the use...
The range of the frequency to be measured by a measurement device depends on the purpose of performing the measurement. The frequency measurement device is built specifically according to its range while the price of the device is proportional to its functions. In this paper, a low frequency measurement device to monitor grid frequency is designed using Arduino technology. All aspects of the design...
Grounding of electrical installation is primarily concern with ensuring safety. The main purpose of grounding is to channel the fault current straightly to earth. To produce a good grounding system, the value of earth resistance must be reduce as low as possible. Otherwise, current may flow through to those who touch the damage electrical equipment instead of flowing through grounding system. In this...
This paper present an approach to estimate the customer load confidence interval using statistical distribution model. Time series data of load profile in the utility of Malaysia was analyze and this data was fit with two statistical distribution models, namely the normal and log-normal distribution. Goodness of fit test was performed in the selection of best model. Result shows that the customer...
