DESAIN DAN IMPLEMENTASI INVERTER DC-AC SATU FASA DENGAN METODE SPWM BERBASIS MODULE EGS002 UNTUK PROTOTYPE PEMBANGKIT LISTRIK TENAGA BAYU (PLTB)

This study proposes an inverter design with a varying input voltage to suit the constantly changing output voltage characteristics of the Pembangkit Listrik Tenaga Bayu (PLTB). The inverter is a device that converts direct current into alternating current so that the electricity produced can be used as emergency power to replace PLN electricity. This study uses the SPWM (Sinusoidal Pulse Width Modulation) method to obtain an output signal in the form of a pure sine wave. In this design, the EGS002 module is used as a SPWM wave signal generator driver and switching process controller on the mosfet. The results of the implementation and testing of inverters with varying input voltages of 11.21V DC - 14.24V DC produce an output voltage of 221V AC - 223V AC and a frequency of 50Hz with no load, with a resistive load power of 25 watts - 100 watts of incandescent lamps. the output voltage is 203V AC – 223V AC and a frequency of 50Hz, while using an inductive load power of 20 watts and 70 watts to produce an output voltage of 219V AC – 223V AC and a frequency of 50Hz. The efficiency of the results and implemented EGS002 inverter is 73%
