Rancang Bangun Inverter Satu Fasa Teregulasi Dengan Teknik Spwm Berbasis Arduino Uno
Abstract
As the demands for electrical energy sources in Indonesia increases, the Indonesian government calls for developing electrical energy sources through the provision of renewable alternative energy power plants which have enormous potential, to be developed in Indonesia. Among them are solar power plants, which are realized using solar cells. An alternative power plant in the form of a solar cell produces a source of DC electrical energy, so an inverter is needed to convert DC electricity into AC so that it can be used. In this research a regulated single-phase inverter with SPWM modulation is designed based on Arduino Uno. This inverter has the ability to convert electricity from 24 VDC to 220V AC with a frequency of 50Hz. The SPWM modulation technique was chosen to produce waves with minimal harmonics so that they resemble waves in AC electricity generated by PLN. The design was carried out by the Proteus 8.11 Professional software and simulation was carried out to see its working ability. The results carried out show the results of the inverter voltage when no load is 231V and the inverter voltage with a 1k ohm resistive load of 216V. The design is stated to be in accordance with the desired specifications, the regulation voltage to the load is still at the level of ± 5%.
Keywords: driver, inverter, SPWM, voltage and current sensors.
