Perancangan Dan Pembuatan Inverter Pure Sine Wave 150WATT Dengan Feedback AC 220/50Hz Berbasis Mikrokontroller Arduino

Abstract

In modern times the development of technology is getting faster, the need for electrical energy is increasing. Now many power plants are being developed using solar energy and with the benefit of Indonesia's geographic location and is located in the equatorial area so that Indonesia has quite a lot of solar energy sources, the utilization of this energy uses a solar cell that uses the working principle of converting solar energy into electrical energy, namely the effect photovoltaic. The output from photovoltaic is in the form of DC voltage. But generally electronic devices generally use AC voltage. For that we need a tool to convert DC voltage to AC, namely an inverter. Inverters have imperfect rectangular and sinusoidal wave outputs and have weak harmonics and low efficiency. This weakness can be overcome by using a pure sinusoidal inverter. To get a pure sinusoidal wave, you can use the Sinus Pulse Width Modulation (SPWM) method.
