Abstract

The use of renewable energy is increasing, thus affecting the rapid use of DC-DC converter technology. The use of a conventional boost converter has a weakness, namely high current ripple. This input current ripple will enter the voltage source, so that the switching noise will spread to other circuits. This problem can be overcome by using a multiphase converter topology that can suppress current ripple. But the conventional multiphase topology has large power losses, because the value of the inductor used tends to be large. Ripple currents will also reduce the efficiency of solar power plants. This study aims to design a four-phase interleaved boost converter that is applied to PV (photovoltaic) with maximum power extraction. The topology method of this circuit is to assemble a conventional boost converter in parallel up to 4 levels, so that it can suppress the input current ripple. This topology modification series also uses the interleaved scaling method in order to reduce heat distribution on each switch. The test method in this study uses a standard boost converter circuit as a comparison, and observes its characteristics and performance through simulation. The converter system is also operated as Maximum Power Point Tracking (MPPT) using the PSO and P&O algorithm controls as a comparison. Based on the simulation results, the MPPT tracking speed has the same speed, which is 2 ms, but the speed to achieve ripple stability in the standard circuit and four-phase interleaved boost converter is 4.5 ms and 6.1 ms, respectively.

Abstract

This community service aims to increase clarity and beauty for all guests who head to the hall in RW 06 Kelurahan Tasikmadu Malang. The method used is deliberation with residents and building managers to determine the design/technique of the construction model for the posts to be installed in the Hall, making posts from stainless steel in the form of plates (stainless steel) and installing stainless steel letters on the west side of the outer wall of the Hall, assessing the robustness and the beauty of the placement, and submission to the Head of RW 06 where the installation of the writing is in his working area. By installing stainless steel letters in the Hall, it is hoped that identity can be made clear to all guests or all parties who pass in front of it. Thus there is a synergy between State Polytechnic of Malang and community members in obtaining satisfaction of the usefulness of assistance and the beauty of the environment in RW 06 Tasikmadu, Lowokwaru, Malang city.

Abstract

Manual work using drilling machines, manual grinding, and filing in penetrating holes in the profile of the hollow Aluminum frame in the shape of the glass door lock housing is the problem faced. Community service aims to obtain a portable door lock children's home hole prototype for hollow aluminum frame profiles for glass doors. The method applied is design discussions with partners, making a hole punch frame for a portable door lock housing for an Aluminum frame profile according to the dimensions of a 3 Ton jack, making a punch in the exact shape of a particular key housing hole with an electric discharge machine (EDM) Wire Cut, hardening and tempering steel punch, making sharp side profiles for the shape of the key housing using a CNC milling machine, trial of punching the door frame profile, and handing over the portable door lock home punch tool kit to the service partner. With the completion of the manufacture of the portable door lock children's home punch tool kit as a work aid, it can be used to support the production of glass door frames ordered by the wider community with good results, a fast process, and production costs can be reduced. In this way, there is a synergy between State Polytechnic of Malang (Polinema) and community members in the production of products needed by the community more efficiently and able to meet the needs of the general community.
