Abstract

In the era of industrial revolution 4.0 expanded digital transformation, such as inverters. The principle of the inverter is to change the DC source to the AC source. The device using an AC source needs a voltage source that is controlled. Hence, the voltage source that is controlled is usually generated from a stand-alone power supply. The stand-alone power supply usually used a conventional inverter. The conventional inverter uses high frequency switching to obtain lower distortion harmonic in output voltage. Another solution is using a five-level inverter that has fewer power switches. The purpose in these research is to make a stand-alone power supply using a single-phase five-level inverter asymmetric topology, which has five power switches to control voltage output based on the standard of IEEE 519. The inverter does sinusoidal pulse width modulation on two the signal reference that was shifting 180 degrees toward the carrier signal. That research has been simulated using Power Simulator software and has been implemented in the laboratory. According to the result of simulation and implementation are generated voltage THD value amount of 4.39%.

Abstract

This study compares the roles of machine learning (ML) and deep learning (DL) in healthcare, focusing on their applications, challenges, and prospects. It addresses the increasing relevance of AI in public health systems and contributes a structured analysis of how ML and DL process different healthcare data types. A systematic literature review was conducted using sources from Google Scholar, Elsevier, Springer, IEEE, and MDPI, applying inclusion criteria based on relevance, publication quality, and recency (2018–2024). Article selection and synthesis using meta-analysis followed the PRISMA framework. The review identified four key application areas: (1) disease outbreak prediction, (2) disease forecasting, (3) disease diagnosis and detection, and (4) disease hotspot monitoring and mapping. ML techniques such as Random Forest and ensemble methods show high performance in handling structured data like patient records, whereas DL architectures like convolutional neural network (CNN) and long-short term memory (LSTM) are superior for unstructured data, including medical imaging and bio signals. Challenges common to both approaches include data quality issues, dataset bias, privacy concerns, and integration into existing healthcare infrastructures. Looking forward, promising directions include explainable AI (XAI), transfer learning, federated learning, and real-time data use from wearable and internet of things (IoT) devices. The study concludes that while ML and DL can significantly improve diagnosis, response to health threats, and resource allocation, maximizing their impact requires continuous cross-sector collaboration, transparency, and ethical governance.
