AC DC Converters

DC-DC converters are devices that convert direct current (DC) energy from one voltage level to another. They can be used to supply variable voltage to circuits, provide regulated current and even to rectify high voltage AC to low voltage DC. One such device is the Tamura TMP 15212C converter. This AC/DC converter offers an efficient and reliable solution for a variety of applications. In this article, we\'ll discuss the application field and working principle of the TMP 15212C.

Application Field

The TMP 15212C is designed to provide a stabilized output voltage that is both low-noise and low ripple. It is especially useful for applications where a stable, low voltage is required such as motor drives, automation equipment, and portable electronics. Additionally, the TMP 15212C is suitable for vehicular and power supplies. It can also be used for uninterruptible power supplies, medical equipment, and control systems. In short, the TMP 15212C is suitable for a range of DC voltage applications.

Working Principle

The TMP 15212C utilizes an insulated gate bipolar transistor (IGBT) rectifier bridge to convert AC input to DC output. This rectifier bridge consists of six IGBTs, which are arranged in a three-phase manner. When an AC input voltage is applied to the rectifier bridge, two IGBTs of each of the three phases turn ON while the rest of the IGBTs remains OFF. This results in the formation of a triangle wave voltage. By smoothing out the triangle wave voltage, the output voltage is converted to DC. The TMP 15212C also includes a controller to offer better accuracy and reliable performance.

In order to meet the multiple usage conditions of its application field, the TMP 15212C adopts a wide input voltage range. This range extends from 85-264VAC, 50/60Hz, with an output voltage range of 3.3V to 24V. It also has an operating temperature range of -25°C to +70°C, with a wide variety of protections for overvoltage, short-circuit, over-current, and over temperature. The TMP 15212C has a maximum efficiency of 80%. These features enable the TMP 15212C to handle a wide variety of applications with high reliability.

Conclusion

The TMP 15212C is a high-efficiency AC/DC converter that is suitable for a wide range of DC voltage applications. It utilizes an IGBT rectifier bridge in order to convert an AC input voltage to a regulated DC output voltage. The TMP 15212C has a wide input voltage range and multiple protections for overvoltage, short-circuit, over-current and over-temperature. With its efficient, reliable and stable performance, the TMP 15212C is an ideal solution for applications where a stable and low voltage is required.
