Electrical Design of a Portable Pure Sine Wave Inverter Using Ferrite Core Transformer and Double Stage Technique

The size of the iron core transformer in an inverter is large and heavy because it has more conductor turns and works at low frequencies. In contrast, ferrite core transformers are designed to work at high frequencies, so the number of turns of the conductor is less, and the transformer size is relatively small and light. Device portability is a significant challenge in designing high-power inverters. This research uses a ferrite core transformer to design a portable pure sine wave inverter. A two-stage technique is proposed in designing the inverter so that the dc-link voltage and capacitor size can be flexibly selected, and the device size can be compacted. The design consists of two stages. First, a circuit to generate a 400-Volt DC voltage is designed using IC SG3525, a MOSFET power amplifier, and a ferrite core step-up transformer. Second, a pure sine wave generator circuit is constructed using an EGS002 module, MOSFETs, and a filter circuit. Experiments are performed by measuring the output voltage, monitoring power and frequency, and observing the waveform with an oscilloscope. The results reveal that the designed inverter can generate a 220-volt pure sine wave output, a maximum power of 500 Watts, a frequency of 50 Hz, and an efficiency between 91.4% to 98.1%

Design of pH Monitoring System for Koi Pond

Koi fish farming has increased significantly and become a promising profession in Bantul, however the farmer faced many challenges to produce good Koi fish. Koi fish productivity affected by water quality as a result of good water treatment and filtering. pH is one of the main indicators for good water quality in Koi farming, whilst not many Koi farmer can afford to buy adequate equipment for their ponds. The purpose of this Community Service Program was to help and empower the community in increasing the koi fish farming productivity. The target group of this project was either groups or persons running micro-enterprises in Koi farming. The specific target of this project is to be able to provide and apply appropriate technology to the community. pH monitoring system was designed to provide cheap and appropriate tools applicable and available in the community. By making the design available for replication, the community can work together to procure goods/systems independently. Therefore, the system designed will not burden the community individually. The targeted koi fish farmers are expected to be role models for other farmers. The results of the manufacture of this precise technology-based tool have been completed with the results of the pH meter monitoring accuracy was higher than 98%. &nbsp

Design of Backpack Sprayer with Electrical Pumping System Using Quality Function Development Approach to Optimize the Agricultural Facility

This paper presents an electric back sprayer based on the attributes required by sprayer users with the Quality Function Deployment (QFD) methodology by optimizing sprayers owned by farmers. In agriculture, the process of crop management and care and pest control is carried out routinely to obtain optimal results. The technical implementation of these efforts is carried out through soil and air media by spraying the plant organs. To keep the pressure and spray results stable, continuous pumping is required. This resulted in certainly more energy needed. Based on the results of research on farmers using a sprayer, the type that is widely used is the type of back sprayer. However, in the use of back type sprayers, farmers still experience problems. Problems encountered in using a back sprayer will be reviewed and overcome by developing a sprayer based on the wishes of the farmer. The design of the back sprayer using the Quality Function Deployment (QFD) method is more appropriate to be used in determining the attributes of the development of a back sprayer following the wishes of the fertilizer sprayer user. The resulting sprayer design is expected to be able to overcome the weaknesses in the back sprayer without having to procure a new sprayer, where the problem of the non-constant pressure level in pumping can be overcome
