This article provides a systematic method for repairing switched-mode power supplies (SMPS), covering common fault symptoms, step-by-step troubleshooting processes, and key repair techniques to help you quickly diagnose and resolve issues.

At the heart of industrial equipment, smart homes, and everyday appliances, there is a small yet crucial component that quietly safeguards our control—this is the push button switch.

Switching Mode Power Supply (SMPS) serves as a core component in modern electronic devices and has become an indispensable power solution for the rapid advancement of the electronics industry. Compared to traditional linear power supplies, SMPS is widely adopted in nearly all electronic equipment due to its compact size, lightweight design, and high efficiency.
This paper will delve into the working principles, topologies, and key design considerations of switching mode power supplies.

DIN rail power supply is a highly efficient power conversion device that can convert AC power into stable DC power. It has advantages such as high power capacity, low energy consumption, and long lifespan. It is commonly used in industrial control cabinets, electrical cabinets, industrial control systems, automation equipment, telecommunications equipment, access control systems, as well as in new energy fields such as photovoltaic power generation and energy storage devices, and in machinery and other fields.

A pure sine wave inverter can output alternating current that closely resembles the utility power waveform, providing stable and clean electricity with minimal electromagnetic interference. It can be safely used for the vast majority of household devices, including precision instruments, communication equipment, and appliances with compressors. In contrast, square wave or modified sine wave inverters have issues such as waveform distortion and harmonic interference, which may affect the normal operation of devices or even cause damage. A 3000-watt pure sine wave inverter can continuously drive a load of about 2400-2500 watts, easily meeting daily needs such as lighting, refrigerators, microwaves, and charging electronic devices. Moreover, a high-quality inverter combines intelligent filtering, multiple circuit protections, efficient heat dissipation design, and low power consumption with high conversion efficiency, making it a reliable power solution to ensure device safety and extend their service life.

In the field of industrial automation and control, accurately detecting and limiting the position of mechanical motion is a key link to ensuring system safety and achieving process automation. As the core actuator for this function, a limit switch's performance directly affects the reliability and efficiency of the entire equipment. The TZ series limit switches, with their excellent design and stable performance, have become the preferred solution in many industrial applications.

With the rapid development of modern industry, industrial control systems play a crucial role in industrial automation. To ensure the stable operation of these systems, industrial control power supplies, as a core component, have also received significant attention. Compared with ordinary power supplies, industrial control power supplies have notable differences in performance and characteristics.

Inverters can convert direct current into alternating current and are widely used in cutting-edge fields such as renewable energy systems, uninterruptible power supplies, industrial machinery, and electric vehicles. They are indispensable components in modern electronic devices and energy systems. Leyu inverters use a more compact design to reduce energy waste and improve overall operational efficiency.
