Shijiazhuang Shuying Instrument Co., Ltd. is a professional company in DC stabilized power supply , and its field is quite prominent. Today we can take a look at the details of the company.

In the past few months, due to the promotion of the telecommunications industry, the supply and demand of DC stabilized power converters have increased. But companies have differing opinions on price trends.

In mainland China, the total market demand in 1999 was $ 3 billion, and it is expected to reach $ 5 billion by 2004. The leading products in the market are small and medium power DC power converters, but manufacturers believe that high density and low voltage products will become mainstream in the next few years.

In Taiwan, due to the continuous upgrade of DC power converters and the introduction of new models, there will also be a large increase in market demand and production capacity. The newly launched products are mainly designed for telecommunications applications, with small and efficient features.

In Hong Kong, most products are used in audio equipment, but manufacturers are also developing devices for telecommunications. In design, the focus is on safety features and improved products.

Models designed for computers, communications equipment, and portable information DC power converters are gaining popularity in Japan. This trend is expected to continue, and companies are working to develop space-saving, efficient, and low-cost models.

The Indian market is also expected to show positive growth. DC power converters are expected to focus on industrial-grade models.

According to the above, DC and DC stabilized power converters have two development directions: miniaturization and high efficiency.

DC regulated power supply is also called DC regulator. Its power supply voltage is mostly AC voltage. When the AC power supply voltage or the output load resistance changes, the direct output voltage of the regulator can be kept stable.

It can be divided into:

① Controllable rectification type. The output voltage is adjusted by changing the on-time of the thyristor.

② Chopper type. The input is an unstable DC voltage. One-way pulsating DC is obtained by changing the on-off ratio of the switching circuit, and then a stable DC voltage is obtained after filtering.

③ converter type. The unstable DC voltage is first converted into high-frequency AC power by the inverter, and then transformed, rectified, and filtered. Then, the new DC output voltage is sampled and the inverter's operating frequency is feedback-controlled to achieve the purpose of stabilizing the output DC voltage.

At present, DC stabilized power supplies are developing in a small, efficient, and digital manner. More and more microcontroller-controlled switching technologies are used, which greatly improves the conversion efficiency of stabilized power supplies and the stability of equipment.

The above is a brief introduction of "summary of DC stabilized power supply". Our company also has DC stabilized power supply, Shijiazhuang Shuying Instrument Co., Ltd. and many other related products. If you are interested, you can contact us for more detailed information!
