Rancang Bangun Inverter Satu Fasa Dengan Monitoring Menggunakan Handphone
ABSTRACT
At present the need for a source of voltage increases in daily activities.The
number of activities carried out outside the home often requires electrical voltage
in an emergency. Inverters are one of the electronic devices that function to
produce AC (Alternating Curent) voltage with input in the form of DC (Direct
Curent) voltage. This study aims to make an inverter that has a voltage source
that can be used to power 1 electronic devices used in everyday life. In addition,
in the future, DC to AC inverters are expected to play an important role in
changing the DC voltage from the latest energy sources such as solar panels that
become AC voltages that are often used in daily activities. This inverter uses the
pulse witdh modulation (PWM) method as a converter from DC voltage to AC
voltage. IC (Integrated Circuit) type CD4047 with the addition of several IRFZ44
transistor components that function as the main control. The transistor is turned
on and off periodically reversing the current in the transformer. The monitoring
system in this inverter circuit uses the Blynk application with a programmed
system. Nodemcu is used to collect several sensor input sources which will then be
connected to wifi so that it is connected to the application. Monitoring functions
to determine the amount of voltage produced. The design of the inverter made
shows the voltage generated by the input from DC voltage in the form of batteries
of 12 volts can produce AC voltage of 210 volts. The test results show that the
inverter has a voltage drop when it gets a load of 300 Watts.
