Abstract

The design of a pure sine wave inverter based on the EGS003 aims to improve the efficiency of electrical energy conversion. This inverter development method integrates PWM (Pulse Width Modulation) control with a pure sine wave reference signal. The use of PWM control allows precise adjustment of the pulse width of the output signal, according to the desired sine wave characteristics. Consequently, this inverter is capable of producing pure sine waves without significant harmonic distortion, enhancing the quality of the generated power and reducing energy losses due to harmonic distortion. This research involves the implementation of EGS003 technology, which is a dedicated PWM controller designed for inverter applications. The use of this controller enables the optimization of resource utilization and enhances energy conversion efficiency. Furthermore, the development of the EGS003-based inverter involves the analysis and design of control circuits in line with modern power electronics principles. This includes adjusting PWM control parameters to various load characteristics, allowing the inverter to operate optimally under different usage conditions. The design results demonstrate that the pure sine wave inverter based on EGS003 provides satisfactory performance in delivering output compliant with power quality standards. With the capability to generate pure sine waves without significant harmonic distortion, this inverter has broad application potential in power systems requiring high-quality power. Additionally, the use of PWM control technology in this inverter facilitates ease of operation adjustment and monitoring, enhancing the overall reliability and efficiency of the system.

Abstract

Brick is a building material that is still widely used by people today. Most of the small-scale brick-making industries print bricks in the traditional way. Of the problems encountered by adding a conveyor as a means of carrying soil that has been printed and then running through the conveyor to the brick makers to add security to the brick makers. The stages of the research were carried out by identifying the problem to produce data from the system to be made, then designing the concept for making the tool. In tool making, the most important components are conveyors, dc motors and PLCs as the main controls in running conveyors. This conveyor works to bring the dough quickly to the craftsmen so that the dough can be measured for the speed of time and the level of safety for the craftsmen. This research has succeeded in creating a "Conveyor Control System in Automatic Brick Making". Conveyor time testing in automatic brick making produces 2 seconds per minute when one brick is on the conveyor and in increasing safety for conveyor makers this can provide good security.

Abstract

Abu Robocon 2019 will be held in the country of Mongolia with the competition theme "The Great URTUU Spreads Knowledge". The 2019 Indonesian ash robot contest made 2 robots, namely MR 1 (Manual Robot) which is run automatically and MR2 (Automatic Manual). In one of the race sessions there was a section of throwing saghai balls. The parameter that must be achieved is the optimization of the embattlement mechanic by landing a throw on target and getting maximum points. The KRAI 2019 robot thrower uses pneumatics. The wind pressure determines the throwing force of the saghai ball. Angle testing to find out the right angle in order to achieve a good and precise on-target throw. Based on the test results of the pitcher's angle of 500, the ball was thrown 20 times resulting in the robot being able to throw well and the average speed was 4.82 m/s. It can be concluded that the angle of 500 is the right angle to produce a lot of 50 points. Testing with a throwing angle of 600, the ball was thrown 20 times resulting in the robot being able to throw, as well as the average speed produced which was 5.20 m/s. The third test with an angle of 700, the ball was thrown 20 times resulting in the robot being able to throw, as well as the average speed produced which was 6.17 m/s. Testing the angle of 500 is the right angle because it can produce a good throw and produce 50 points.
