51306673-100 EPNI HONEYWELL 电源模块

51306673-100 EPNI HONEYWELL 电源模块是一种可以直接贴装在印刷电路板上的电源转换器，按变换方式一般分为AC转DC或DC转DC。随着科技的发展，电源体积趋向模块化和小型化，于是出现了电源模块。其集成度最高，将开关电源的主要电路集成在芯片中，可以实现宽频调制、隔离及多种保护等功能。

常见的基本原理由以下部分组成，输入整流滤波器，包含整流桥和输入滤波电容。单片开关电源，包括功率开关管、控制器及MOSFET。还有高频变压器、漏级钳位保护电路、光耦反馈电路、输出整流滤波器、偏置电路等部分组成。

51306673-100 EPNI HONEYWELL 电源模块通时输入整流波器一般可以适配交流85~265V或直流100370V的输入电压河用，频率有47400选择，常规一般为50/60Hz。因为它具有小体积、高集成度、高性价比和最佳性能指标，只需要最简的外围电路，配上少量分立式元件即可使用。并且拥有高效率、高可靠性、设计灵活等优点，现已成为开发设计中小功率开关电源的优选集成电路.

51306673-100 EPNI HONEYWELL 电源模块方案的技术要求低，设计简单，占用空间小，可靠性高，并且可随时变换方案。当产品设计需更改时，只需并联或替换电源模块即可。因此广泛应用于工控、机械设备、船舶、航空航天、通讯、军工、数据通信、手持电子产品、仪器仪表、LED照明、智能化、电力、铁路、安防、矿业、医疗、汽车电子等多个领域。目前单个电源模块几乎很难通过SURGE、EFT、CE、RE等EMC实验，尽管国外的产品寿命长、可靠性高、EMI控制很好，但是其抗干扰性的性能仍不够强。开关电源大多数是通过UL及3C认证的，EMI性能是有保证的，但是模块化后不通过是因为测试EM的方法，想要让设备通过EMC测试还需做好外围电路设计。

选择电源模块最好是选择功率在所用的30 - 80%为宜，一般这个功率范围内其各项性能发挥稳定可靠。等级分类主要有商用级、工业级和军用级，不同的等级对工作温度、震动、湿度等要求不同。为了保证产品长期稳定可靠的工作，因此在选择产品时，要考虑实际应用环境。

51306673-100 EPNI HONEYWELL power module is a kind of power converter that can be directly mounted on the printed circuit board, which is generally divided into AC to DC or DC to DC according to the conversion mode. With the development of science and technology, the volume of power supply tends to be modular and miniaturized, so power supply module appears. It has the highest integration, and the main circuits of switching power supply are integrated in the chip, which can realize the functions of broadband modulation, isolation and various protections.

The common basic principle consists of the following parts: input rectifier filter, including rectifier bridge and input filter capacitor. Single-chip switching power supply includes power switch tube, controller and MOSFET. It also consists of high-frequency transformer, drain clamp protection circuit, optocoupler feedback circuit, output rectifier filter, bias circuit and so on.

The 51306673-100 EPNI HONEYWELL power module can generally adapt to the input voltage of 85~265V AC or 100370V DC, and the frequency is 47400, which is generally 50/60Hz. Because it has small volume, high integration, high cost performance and the best performance index, it can be used with the simplest peripheral circuit and a few discrete components. It has the advantages of high efficiency, high reliability and flexible design, and has become the preferred integrated circuit for developing and designing small and medium power switching power supplies.

51306673-100 EPNI HONEYWELL power module scheme has low technical requirements, simple design, small occupied space, high reliability and can be changed at any time. When the product design needs to be changed, just connect or replace the power module in parallel. Therefore, it is widely used in industrial control, mechanical equipment, ships, aerospace, communication, military industry, data communication, handheld electronic products, instruments and meters, LED lighting, intelligence, electric power, railways, security, mining, medical care, automotive electronics and other fields. At present, it is almost impossible for a single power module to pass the EMC experiments such as SURGE, EFT, CE and RE. Although foreign products have long life, high reliability and good EMI control, their anti-interference performance is still not strong enough. Most switching power supplies have passed UL and 3C certification, and EMI performance is guaranteed. However, after modularization, they failed because of the method of testing EM, and peripheral circuit design is needed to make the equipment pass EMC test.

It is best to choose the power module at 30-80% of the used power. Generally, its performance is stable and reliable within this power range. There are mainly commercial grade, industrial grade and military grade, and different grades have different requirements for working temperature, vibration and humidity. In order to ensure the long-term stable and reliable work of products, the actual application environment should be considered when selecting products.
