DC/DC converters are an important link in power electronics products and are very common in electronic products today. In order to meet the needs of different purposes in practical applications, different types of DC/DC converters need to be selected. In this paper, we will discuss the application field and working principle of an important DC/DC converter, the SD-350C-24.
The SD-350C-24 is a 2-in-1 DC/DC converter module that combines isolated flyback converter and non-isolated step down DC/DC converter. It has 24V input, 350W/10A output, and is able to work in full load up to 75℃ without step-down. With its multifunctional feature, it can be used in a variety of applications such as industrial control, communication system, motor drive, small and medium sized UPS systems, etc.
The main feature of this type of DC/DC converter is that it uses an isolated flyback converter and a non-isolated buck DC/DC converter in combination. Its output is divided into two parts, one part is used as the isolated flyback output, while the other part is used as the non-isolated buck output. The flyback output can provide unlimited isolation, high efficiency and good stability. The non-isolated buck output has no isolation, but can provide low cost, low ripple and high efficiency.
The working principle of the SD-350C-24 is as follows: first, the AC power is rectified into DC power. Then, the DC power is converted into high-frequency AC power. After that, the high-frequency AC power is changed into low-frequency AC power and DC power through a transformer. Finally, the DC output voltage is adjusted through a buck regulator. The output voltage level can be adjusted by adjusting the duty cycle of the buck regulator.
In summary, the SD-350C-24 DC/DC converter is a useful and multifunctional type of DC/DC converter that can be used in a variety of applications. It has a combination of an isolated flyback converter and non-isolated buck DC/DC converter, and its working principle involves several stages of AC and DC power conversion. Its output voltage level can be adjusted by simply adjusting the duty cycle of the buck regulator.
