<![CDATA[Multilevel Inverter (MLI) is a converter that converts DC power source into AC power source with voltage output more than 2 levels. The conventional 5-level Multilevel Inverter Topology that is developing today generally uses eight power switch components. In this paper, research Topology multilevel inverter 5 levels was conducted by reducing the power switch components into four pieces and assisted by two diode clamps and capacitor as voltage coupling. PWM (Pulse Width Modulation) technique used to utilize multicarrier modulation. Simulation testing with MATLAB conducted has been verified with the results of hardware tests where the output voltage shows similarity of shape at the output voltage MLI 5 levels. The results and discussion of the proposed topology can provide economic benefits from the use of the number of power switch components (MOSFET) compared to conventional 5-level MLI topology.Keywords :Â Multilevel Inverter, PWM, 5 Level]]>

<![CDATA[Switching techniques have been continued to develop, including sinusoidal PWM, space vector PWM, current tracking PWM, harmonic elimination PWM and others. Each method has advantages and disadvantages, but the most commonly used methods are sinusoidal PWM and space vector PWM. PWM that is generated using a microcontroller or analog IC component generally has a maximum voltage value of 5V. To strengthen the PWM wave, a gate-driver circuit is needed, so that the PWM control wave is able to move the IGBT / MOSFET. On this paper, the design of gate driver circuit use An analog IC, which starts from the generation of two waves, namely a sinusoidal wave and a DC source to be compared (Comparator) so that it can produce a PWM wave. Then this PWM wave is isolated using an optocoupler and MOSFET driver IC to limit interference in the switching process on high power supplies. Based on the results, it can be cancluded PWM control wave output from the gate-driver circuit is isolated from the system intended for designing a power converter and other applications.]]>

<![CDATA[Solar or solar energy can be an alternative source of energy in the future, where solar energy can be converted into electrical energy by utilizing the photoelectric effect that occurs in photovoltaic components or solar cells. Solar cells or photovoltaic components can convert sunlight into electrical energy that can be used directly by the load or stored in a battery, a kind of electrochemical device that can store electrical charges in the form of chemical energy. The electrical energy generated by the solar cell is influenced by the intensity of light received by the sun. To gain the desired power and voltage, the solar cells are connected in series and parallel into a solar cell module. 2N3055 & MJ2955 transistor based solar panels are the basic materials for designing alternative power generation. In the process of manufacture, this solar panel utilizes the components of used components that are still feasible to use, so it can be used to be the appropriate technology to produce a solar panel that utilizes solar energy in the form of sunlight and solar heat. In this study also conducted experiments using glass components as a reflection effect from light sources. The result of this experiment obtained that the amount of electrical energy output resulting from the reflection effect of light by using 2N3055 transistor and MJ2955 transistor can produce increased current and increase electrical power.Keywords: Solar cell, Transistor 2N3055 & MJ2955, The effect of reflection light]]>

Generally, remote rural areas located in mountainous areas have a large potential of water energy, so that the hydroelectric power plant is one of the energy sources that can be developed. Jambi is an area covered with Batanghari River flows. This research aims to know how the work process of Microhydro power plant. Components of the essential components of miniature microhydro power plants are reservoirs, rapid pipes, turbines, generators where these components are not loose bias, interrelated to one another. Round of Tubin obtained from the experiment is 400 rpm with water discharge 0.0016 m3/s. The maximum voltage generated by the generator is 18 volts. Voltage generated from the generator to charging the Batrai used inverter of 13.1 volts. The load will remain on even though the main energy source is the generator stop in the same, because the energy of the second is Batrai.]]>

<![CDATA[Variable speed drives and the importance of controlling the speed of existing motors have attracted much attention with the advent of new electrical devices and magnetic materials. This paper is a comprehensive review of the application of VFD in energy saving electric motors. The aim is to identify energy saving opportunities and apply variable speed drives to existing electric motor applications. In this paper the authors hope to provide useful information for future variable speed drive applications such as fans, pumps, coolers, ventilators and as electric car propulsion. In this study, a series of frequency changes has been tested as an induction motor speed regulation (VFD), which in the results of this frequency change research can regulate the speed of the induction motor. In this study, the frequency change is still regulated analogously by changing the resistor size on the PWM signal generator IC for the MOSFET driver. For that the next research is expected to change the frequency can be done digitally]]>
