RANCANG BANGUN DAN PROTEKSI INVERTER PURE SINE WAVE SPWM 500 WATT BERBASIS MIKROKONTROLER MENGGUNAKAN FUZZY LOGIC

Abstract

The application of power electronics is growing in the DC to AC converter system often called (Inverter). The inverter system utilizes a DC voltage source generated by a battery, power supply, or other DC voltage source, which will later be converted to AC voltage by the inverter. The development of microcontrollers as a driver for generating PWM signals on inverters encourages us to continue to develop. One of the developments of the microcontroller is ESP32. This study aims to produce a single-phase inverter with a pure sine wave output using the ESP32 driver as the SPWM signal generator. Besides that, to maximize the performance of the inverter, it is necessary to add a protection system to reduce the risk of damage to the inverter or the load. The use of fuzzy method is used to stabilize the voltage.
