Introduction

Boost converter is a type of DC-DC converter that plays a crucial role in raising DC voltage from one level to another. This tool is highly beneficial in various applications, ranging from charging solar panel batteries, DC motor speed regulation, DC motor braking system (braking), to wind power plants connected to the electricity network. Despite having numerous benefits, Boost Converters often experience problems with unstable output waves, especially during start-ups, where phenomena such as overshoot and long settling time occur.

Understanding the Problem

The transient problem, although it cannot be fully eliminated, can be minimized by controlling using Pulse Width Modulation (PWM) in the Boost Converter. However, traditional PWM control methods often struggle to provide optimal results, leading to unstable output waves and inefficient performance. This is where Fuzzy Logic Control comes into play, offering an innovative PWM control method to improve the performance of Boost Converter.

Fuzzy Logic Control: A Novel Approach

Fuzzy Logic Control applies the Mamdani method consisting of two inputs, namely error (E) and changes in error (CE), as well as one output which is a duty cycle. By using Matlab® Simulink software, a number of trials are conducted to assess the effectiveness of this method. The test results show that by applying Fuzzy Logic Control as a PWM controller, overshoot can be removed at a reference voltage of 40 V, 50 V, and 60 V.

The Benefits of Fuzzy Logic Control

The use of Fuzzy Logic Control also managed to reduce the settling time value significantly. For a reference voltage of 40 V, the settling time is reduced from 15 ms to 0.540 ms. As for the reference voltage of 50 V, the settling time is reduced from 16 ms to 0.610 ms, and for 60 V, from 19 ms to 0.690 ms. This drastic decline shows the effectiveness of Fuzzy Logic Control in optimizing the performance of the Boost Converter, which can contribute to increasing the efficiency of power systems.

Further Analysis and Implications

Further analysis of these results revealed that the application of Fuzzy Logic Control not only provides solutions to the transient problem faced by Boost Converter, but also shows great potential in other applications that require stable and responsive control of change. This provides a new direction for the development of a more sophisticated and adaptive control system in the field of power electronics.

The Future of Fuzzy Logic Control

In the conclusion, this study confirmed the importance of the application of Fuzzy Logic Control technology in controlling PWM in the Boost Converter. With results showing a significant reduction in overshoot and settling time, this method is feasible to consider in the design of control systems in various electricity and electronic applications. In the future, further development and implementation of this method can have a positive impact on the industry, especially in improving the efficiency of the power system that is growing.
