When we choose a power module, we generally look at the quality of the input, output, ripple, breakdown, temperature, certification, and other characteristics of the power supply. Apart from these, we can also judge according to the following points.
1. Circuit principle and soldering process The bare board can use intuitive methods, such as a neat layout of components and potting modules without being exposed and unable to view the internal situation. The quality of the mechanized wave soldering process is better than manual soldering, generous, but Better in terms of safety and performance
2. The core of the power supply of chip components and transformer components is IC, which will directly affect the power and high-temperature resistance of the entire power transformer components. . Responsible for accomplishing AC-DC and saturating the fryer during energy overload.
3. Is it an electrolytic capacitor or a ceramic capacitor?
1）. The electrolytic capacitor is a temperature-sensitive component after the electrolyte heats up and explodes.
2）. Ceramic capacitors are mainly non-polar, and the switching frequency will cause the parasitic resistance of the capacitor to heat up. Good dielectric materials and capacity should not be too large. Most, it is widely used in high-frequency circuits.
4. Batch testing of aging and high-temperature aging No matter how good the quality stability of product materials and production process control is and whether the materials have potential safety hazards, aging needs to be detected. Only through power aging and high-temperature pumping detection.
The benefits of choosing a China Small size power module manufacturers
Power savings of up to 25% can be achieved with these new power switches, and the reduction in power consumption brings many improvements. On the one hand, the heat dissipation design of the heat sink and the overall module can be more compact and have higher cost performance. Providing the same output power but with a smaller product is an important advantage, especially in pump or fan designs. In general, by using smaller electronic drives, controlled motors can be used in applications that were not possible before. Also, reduced use of production materials means lower costs for production, transportation, and recycling, which all boil down to product life cycle costs.
On the other hand, the maximum output power can be increased while maintaining the consistency of the existing design parameters. Products that use the same thermal design but consume less power have higher reliability, because there is a less thermal excursion, and the failure rate is greatly reduced. Moreover, the same design can evolve into a variety of different models by simply replacing different output power chips, thereby shortening the time to market.

AC-DC Converter Module: Efficient Power Conversion Solution
Introduction The AC-DC converter module is a circuit board that converts alternating current (AC) to direct current (DC) in a power supply system. It is an essential component for many electronic devices and systems that require a stable and regulated DC voltage. The AC-DC converter module is designed to be highly efficient, reliable, and cost-effective for use in a variety of applications. Efficient Power Conversion Solution The AC-DC converter module provides an efficient power conversion solution compared to traditional linear power supplies. Linear power supplies use a transformer to step down the voltage and then regulate the output voltage using a linear regulator. This method is inefficient and produces a lot of heat, resulting in a lower power efficiency. On...
