As energy regulations tighten and industrial systems become increasingly digitized, the challenge of improving energy efficiency while maintaining system stability has become a critical concern in power supply design. Power Factor Correction (PFC) is one of the key technologies for achieving high power utilization efficiency and stable power systems.

In precision industrial applications such as chemical dosing, water treatment, and process control, dosing pumps are the preferred choice thanks to their high accuracy, low maintenance, and easy integration. This case study comes from a European renowned customer, who faced design challenges when developing their next-generation dosing pump control module.

With the rapid growth of smart manufacturing, electric vehicles, and IoT applications, the demand for high reliability in switching power supplies is rising significantly. A switching power supply must not only deliver stable output voltage but also maintain reliable performance over long periods of operation. As a result, lifespan estimation and thermal management have become two critical aspects of power supply design.

This article explores how to extend the service life of switching power supplies and enhance system stability through three core perspectives: lifespan-determining factors, thermal design considerations, and key component selection.

As smart city infrastructure continues to expand, the demand for reliable and efficient power solutions grows accordingly. In applications such as communication systems, pre-warning systems, sensors, and lighting, stable power supply is essential for maintaining system functionality. The ARCV60 Series 60W AC-DC Power Module from ARCH Electronics delivers outstanding performance and compact integration, successfully supporting various smart city deployments by our clients.
