TEWS TVME200 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。电源模块通过输入整流滤波器一般可以适配交流85~265V或直流100370V的输入电压范围,频率有47400Hz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.

选择TEWS TVME200 电源模块的技术要求低,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。

TEWS TVME200 power module is a power converter that can be mounted directly 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 supplies tends to be modular and miniaturized, so there is a power module. The main circuit of the switching power supply is integrated in the chip, which can realize the functions of broadband modulation, isolation and a variety of protection.

The common basic principle consists of the following parts, the input rectifier filter, including the rectifier bridge and the input filter capacitor. Monolithic switching power supply, including power switching tube, controller and MOSFET. There are also high frequency transformer, leakage clamp protection circuit, optocoupler feedback circuit, output rectifier filter, bias circuit and other parts. The power module can generally adapt the input voltage range of AC 85~265V or DC 100370V through the input rectifier filter, and the frequency is 47400Hz, and the general frequency is 50/60Hz. Because it has a small size, high integration, high cost performance and the best performance indicators, only the simplest peripheral circuit is required, with a small number of discrete components can be used. And has the advantages of high efficiency, high reliability, flexible design, etc., has become the optimal integrated circuit for the development and design of small and medium power switching power supply.

The selection of TEWS TVME200 power module has low technical requirements, simple design, small space occupation, high reliability, and can be changed at any time. When the product design needs to be changed, just parallel or replace the power module. Therefore, it is widely used in industrial control, machinery and equipment, ships, aerospace, communications, military, data communication, handheld electronic products, instruments and meters, LED lighting, intelligence, electric power, railway, security, mining, medical, automotive electronics and other fields.
