The student who made the title of this Final Project was Bagus Setyo Nugroho from the D4 Ship Electrical Engineering Study Program.

Electrical energy is currently an energy that is needed in everyday life from households to the industrial realm. By utilizing renewable energy such as photovoltaics, wind turbines, or other renewable energy as electrical energy plants, it can reduce the use of non-renewable energy. This generated energy is generally stored in batteries in the form of direct voltage (DC). To be used by electrical equipment, it is necessary to change from DC voltage to 220 volts alternating voltage (AC). Changing this voltage requires a device called an inverter. In the inverter, the DC voltage is converted into AC voltage in the switching process of the semi-conductor switch. However, because most inverters have a drawback in the high Total Harmonic Distortion (THD), the voltage drop is still high if subjected to load.

So in this Final Project, the author wants to solve the voltage drop problem that occurs in the inverter by designing and building a 1 Phase Inverter With Zeta Converter as a Voltage Stabilizer Using the Proportional Integral (PI) Control Method. By adding a zeta converter circuit as a voltage stabilizer. Zeta converter will work when the voltage from the battery decreases, then this zeta converter will increase the voltage according to the set value that has been set by controlling the PWM signal. This PWM signal is set by the PI control according to the error data from the zeta converter output feed back voltage. The output voltage of the zeta converter will be the input voltage for the inverter circuit controlled by the SPWM signal. PWM, as well as SPWM signal generation is generated by the program from STM32F103. The voltage that has been inverted will be increased to AC voltage 220Volt so that it can be used by electrical equipment.
