Abstract

This study describes the effect of the collector cross-sectional area on the capacitance value of the four graphene super capacitors using a digital multimeter. In the first experiment, the graphene square super capacitor with a cross-sectional area of 25 cm2 resulted in a capacitance of 0.842 F. Especially the super capacitor, which is called a double layer electric capacitor (EDLC) or ultra capacitors, meet the standards for high power applications. The use of supercapacitors is very rare because of the high cost of manufacture. The graphene super capacitor that has the best capacitance is Square. The graphene super capacitor in this study was designed in several stages. Synthesis of graphene as electrode was obtained by mixing H2SO4, H3PO4, KMnO4, Graphite Powder, dried for 12 hours at 110ºC

Abstract

This study aims to produce an inverter which is implemented in a solar power plant for residential homes. In a solar power generation system, an inverter is a device that functions to convert direct current into alternating current. In this study, an inverter was designed to produce an electrical output that was in accordance with the needs of residential electrical equipment. The design shows the important role of the microcontroller as a control unit and the IGBT component as a power electronics component. The test results show that the inverter has been able to produce an output with a voltage of 220 V and a frequency of about 50 Hz with a sine wave output, but there are stillbroken wave.As of this writing, improvements are still being made.
