AC DC Converters

DC-DC converters, commonly referred to as AC-DC converters, are electronic devices that can convert a given alternating current (AC) input into a direct current (DC) output. This type of equipment is used to power various electrical systems, such as computers, electronic devices, and motors. In this article, we will discuss the RAC15-15DB application field and working principle.

The RAC15-15DB AC-DC converter is a high-performance buck converter used to convert AC input power into a regulated DC output. The RAC15-15DB features a wide input voltage range (16~30VDC), adjustable output voltage and current limit, and high efficiency. It is suitable for many applications, such as small inverters, LED lighting systems, solar panel systems, UPS systems, and battery chargers. It is also designed for use in harsh environments, such as high-temperature and corrosive atmospheres.

The basic working principle of the RAC15-15DB is as follows. An AC input is connected to the input of the converter. The input passes through a rectifying diode bridge, which converts the AC input into a single phase DC voltage. This DC voltage is then passed through the converter’s main switching element, typically a MOSFET transistor. The voltage is then passed through a power factor correction (PFC) stage, whose purpose is to increase the overall power factor of the system. An inductor is then connected to the output to store energy during the conversion process.

The stored energy then passes through a secondary switching element, such as an IGBT or MOSFET transistor. This allows the RAC15-15DB to convert the incoming DC voltage to a different output voltage by controlling the on/off state of the switching elements. The output voltage is then controlled using pulse width modulation (PWM) control, which is a form of digital control that uses pulses of varying widths to regulate the output voltage.

The RAC15-15DB also has a number of features that make it particularly suitable for harsh environments. It is designed to withstand temperatures up to 105℃, and it is certified to IP67, withstanding dust and water immersion for up to a month. It also has built-in overvoltage and overcurrent protection, ensuring the safety of both the converter and the system it is powering.

In summary, we have discussed the RAC15-15DB AC-DC converter. The RAC15-15DB is an advanced buck converter suitable for a variety of applications, including harsh environmental conditions. It is easy to use and features adjustable output voltage and current limit, high efficiency, and built-in protection. We hope this article has been helpful in understanding the application field and working principle of the RAC15-15DB.
