Metalpushbutton Switches Development Trend
Jul 04, 2017

Metalpushbutton switches development trend

First, the development trend of switching power supply industry

With the rapid development of China, the switch industry has become an indispensable part of the electronics industry. There are many types of switches, such as: temperature control switch, rotary switch, straight key switch, button switch and so on. The The Today, the development trend of switching power supply industry Brief analysis:

1, switching power supply product development trend

A, green

Green switching power supply products will be widely used. Green switching power supply products specifically refers to significant energy savings and no pollution to the electricity network. The 21st century nodes and environmental requirements, will enable a variety of intelligent switching power supply technology is widely used, so that the power supply structure from centralized to distributed development.

B, miniaturization

Small high-frequency switching power supply and its technology to become the mainstream of modern power supply system. The miniaturization of power supply, weight reduction is particularly important for portable electronic devices such as mobile phones, digital cameras, and so on. Therefore, to improve the switching power supply power density and power conversion efficiency, making it small, lightweight, is the people continue to strive for the goal. High frequency, soft switching technology as one of the main technical means of miniaturization of power supply, in recent years is one of the hot spots in the international power electronics industry.

C, digitized

The digital power supply combines the efficiency of the switching power supply with the intelligent control of the digital chip, and uses the appropriate algorithm to adjust the voltage and current. Digital power compared to the analog power supply, the current detection error can be accurate digital correction, voltage detection more accurate; can achieve fast and flexible control design.

D, integrated

In order to improve the reliability of the system, machine manufacturers and component manufacturers to develop "user-specific" power module has become a trend. That is, almost all the hardware of a machine have been installed in the form of a module, so that a large number of components are no longer between the traditional lead connected to the parasitic parameters to a minimum, so the power components and power The device to withstand the electrical stress to a minimum, to improve the reliability of the system equipment purposes.

2, switching power supply market prospects

China Power Society and ICTresearch predicted that by 2015 China's power industry output value will reach 215.6 billion yuan, 2011-2011 average annual compound growth of 13.39%.

With the power gradually to the miniaturization, thin, lightweight, high frequency direction, can be expected in the future with light, thin, small and high-frequency switching power supply output growth will be higher than the entire power industry output growth. China Power Society is expected to 2011, the national switching power supply output value will reach 128 billion yuan in 2015, China's switching power supply output value will reach 187.5 billion yuan.
