Abstract :
Many energy sources including the latest energy sources are first
converted into electrical energy before being used by users. Making three phase
inverters, the source of making 220 AC pln inverters is changed using diodes or
rectifiers to DC voltage, making these inverters requires an arduino uno
component as a PWM signal to the inverter to change the voltage as instructed.
PWM is a mechanism to generate an output signal that repeats a period between
high and low where we can control the duration of the high and low signals as we
wish. The use of the PWM method is also very diverse including to regulate the
output of a power conversion device so that it can produce an output voltage that
can be adjusted frequency. This PWM signal is controlled through Arduino Uno,
from the test results obtained netral phase, frequency 50 Hz 0.99, frequency
300Hz 3.41. While the phase to phase frequency is 200Hz 2.47, the frequency is
500 Hz 5.62.
