Boost Converter;
Investigation; PID; Fuzzy
Logic; Simulink
Boost Converter is one type of DC converter that is often used
for various purposes where the output voltage is equal to or
higher than the input voltage. To get an output voltage higher
than the input voltage commonly used by electrical and
electronic equipment, a voltage increase is needed that can be
varied as needed. One way to increase the voltage with a
variable is to use the Boost Converter with Fuzzy Logic
control. This research proposes a Boost Converter that can
increase the variable direct voltage. Boost Converter
proposed Fuzzy Logic using Mamdani's rules as a controller.
Boost Converter is investigated on Open Jacks Boost
Converter, Closed Loop Boost Converter and Boost Converter
Fuzzy Logic Control Duty cycle on Boost converters using PID
and Fuzzy Logic implemented using Simulink Matlab. The
results of the investigation show that the Boost Converter
designed in this study has worked well according to the
purpose.

1. Introduction
Due to population growth and societal progress, the consumption of electrical energy is
increasing, which leads to a decrease in the availability of fossil fuels. The use of power electronics
converter technology in everyday life is increasing along with current technological advances; one
example is the application of DC converters that utilize the Boost Converter technique. With this boost
converter system, you can meet the requirements of variable output voltage sources by using non-
insulating switching-type DC regulators (Hushaini et al., 2019; Setiawan & Yuhendri, 2020). You can
set the output voltage value to be higher than the input voltage value.

A converter that raises the DC voltage is known as a boost converter. If the voltage requirement
of an electronic device exceeds the available power supply voltage, then this circuit functions as a
power source.
Figure 1 Boost Converter
Boost converter This research utilizes fuzzy logic control and several Pid control techniques
(Harselina & Hendri, 2019).
PID control is often used and taught widely in university control systems courses. This is due
to the closed-loop control mechanism on the system, which is easy to use and can be operated with
other control mechanisms. There are three control methods in PID control systems: P (proportional),
D (derivative), and I (integral). Each control approach has its pros and cons (Ali, 2004; Diaz et al.,
2019; Li et al., 2006).

Logic that has fuzzy value or similarities between right and wrong is called fuzzy logic. A value
in fuzzy logic theory can be true and false at the same time (Jati et al., 2020). But the weight of a
person's membership determines how much existence and guilt he has. The three main principles of
fuzzy logic are fuzzification, rule base, and defuzzification (Nasution, 2012; Saelan, 2009).

Table 1 shows that the output voltage can be increased using the Boost Converter. However, efficiency
figures and output voltage remain erratic based on the value of the duty cycle used. But in the end,
the greatest efficiency produced was worth 137% (Arvianto et al., 2020; Nurwati et al., 2022).

By providing a progressive increase in input voltage, simulation testing of the Closed Loop Boost
Converter circuit with PID control was carried out. While resistors (R), capacitors (C), and
inductors (L) all have the same value as in the previous circuit (Putri & Aswardi, 2020).
The value of the constant Kp is 0.01, the value of the constant Ki is 50, and the value of the
constant Kd is 0. PID tuning is automatically performed using MATLAB software to determine
the value of the PID constant.

c. Fuzzy Logic Control Boost Converter,
With a fixed input voltage of 5 volts and a gradually increased frequency, the Fuzzy Logic
controlled Boost Converter circuit was simulated and tested. The values of resistors (R),
inductors (L), and capacitors (C) used in this circuit are the same as the values in the previous
circuit (Sirait & Matalata, 2018).
MATLAB control parameters for Fuzzy Logic systems are configured in such a way that enables
optimal performance.

and provide a relatively high-efficiency value, with a value of >83%. In addition, when the frequency
rises, the output voltage value also rises. However, an error occurs when the frequency is set to 4000
Hz.

4. Conclusion
Open-loop Boost Converter Investigation The output voltage of a circuit with a fixed input
voltage of 12 V and the Duty Cycle value gradually increases, the Outgoing Voltage increases as the
Duty Cycle increases. This means that the final output voltage is determined by the Duty Cycle value.
The Closed Snap Boost Converter with PID control technique can produce a high-efficiency value of
>63% and increase the applied voltage. In addition, when the input voltage rises, the output voltage
value also rises. The fuzzy logic control Boost Converter can increase the applied voltage and provide
a relatively high-efficiency value, with a value of >83%. In addition, when the frequency rises, the
output voltage value also rises. However, an error occurs when the frequency is set to 4000 Hz.
