Abstract

An inverter is an electronic device that functions to convert direct current (DC) voltage into alternating current (AC) voltage. In this design, a single-phase inverter is developed to convert 12V DC into 220V AC using a PWM IC type CD4047BE as the pulse signal generator. The CD4047BE is operated in astable mode to produce a symmetrical square wave signal, which is then amplified and used to control power transistors or MOSFETs that act as switching devices for the step-up transformer. The transformer increases the output voltage up to 220V AC. This system is designed for small-scale applications such as emergency lighting or light electronic devices. Testing showed that the inverter circuit is capable of generating AC voltage with a frequency close to 50 Hz and a waveform that approximates a square wave. These results indicate that the CD4047BE is effective as a PWM controller in a simple inverter system.

Abstract

Waste management is still a major challenge in various regions, especially in densely populated urban areas. One of the main problems is the lack of public awareness in sorting waste based on its type, such as organic, inorganic, and metal waste. As a result, waste that should be recycled or reprocessed instead piles up in landfills, polluting the environment, and accelerating ecosystem damage. To overcome these problems, innovative solutions are needed that can help the waste sorting process automatically and efficiently. Microcontroller-based automation technology is one promising approach in this field. Arduino Uno, as one type of microcontroller that is popular and easy to use, allows the design of smart systems with affordable costs and high flexibility.
