In the current rapid development of electronics, Arduino microcontrollers are often used in electronic devices, one of which is inverters. An inverter is a device that can change direct electric current (DC) into alternating electric current (AC). To get a pure sine wave on the inverter, you can use a DC wave signal width modulation technique called SPWM (Sinusoidal Pulse Width Modulation), because of its advantages in producing low harmonic interference. This method is carried out by combining two square waves as a carrier signal of 10 KHz and a reference signal of 50 Hz. The reference signal and carrier signal are generated using the Arduino Nano microcontroller, by amplifying the SPWM signal using IC IR2110, so that it is able to carry out the switching process on the Full-bridge inverter circuit using the IRF3205 Mosfet component and the inverter voltage is increased with a 7V/220V 10A step-up transformer so that expected to produce an AC voltage of 220 V with a sine wave frequency of 50 Hz.
