High-power electronic power devices are repotted into an integrated module according to a certain combination of functions. Semiconductor Module Devices,Power Semiconductor Device,Semiconductor Cooling Devices,Diode Module YANGZHOU POSITIONING TECH CO., LTD. , https://www.yzpst.com
A power semiconductor module is a combination of certain functions and modes, and a power semiconductor module is a high-power electronic power device that is re-potted into a whole according to a certain function combination. Power semiconductor modules can achieve different functions according to the different components in the package. Power semiconductor modules can be used as air-cooled modules with air-cooled heat dissipation, and water-cooled modules with water-cooled heat dissipation.
It is characterized by simple installation, convenient use and maintenance, small size and light weight.
Typical applications in AC/DC motor control, various rectifier power supplies, industrial heating control, dimming, non-contact switches, electric welding machines, motor soft start, reactive power compensation, frequency converters, UPS power supplies, battery charging and discharging, etc.
Although there are more and more things on our mobile phones, wonderful photos and videos, video applications that are installed at random, etc., the mobile phone's screen is too small to be shared by the whole family and is not as refreshing as the big screen. What should I do? Just a few simple steps, the small screen instantly becomes larger.
Mobile phone screen television mainly has two kinds of wireless and wired methods, let's talk about wireless:
One, wireless connection
The use of wireless connection must first ensure that the TV is a smart TV. In addition, the mobile phone and the TV need to remain in the same WiFi network state. Apple and Android devices are slightly different.
1, Apple equipment
Swipe up from the bottom of the phone screen to open the "control interface" and click on the "AirPlay mirroring" option. You can see the name of the TV directly. After you click on it, the TV will display the screen of the phone.
2, Android devices
Take the Xiaomi mobile phone as an example, first open the “Wireless Screen†or similar Miracast application on the TV, and then turn on the “Wireless Display†in the wireless connection mode of the mobile phone. Then the name of the TV will appear on the mobile phone. The phone can be displayed on the same screen as the TV.
If you are playing TV shows, variety shows, etc. in APPs such as Youku and Tencent videos, clicking on the "TV" button will display the TV name. Clicking on it will make the screen successful. This operation is not different from the Android phone.
Second, wired connection
The wired connection needs to use the HDMI or VGA interface of the TV. The HDMI interface needs the MHL function. It refers to the Mobile High-Definition Link (Mobile High-Definition Link) interface. Generally, this symbol will be displayed on the interface. In addition, mobile phones also need to support MHL functions, but recently it seems that fewer and fewer mobile phones support MHL.
1, Apple equipment
Apple devices need to use Lightning digital video converter or Lightning to VGA converter, the official price is 388 yuan, and then use an HDMI / VGA cable can be connected to the TV.
2, Android devices
Android phones need dedicated MHL lines, which are cheaper than the above Lightning converters, and the connection methods are similar, but they say more.
In fact, both economical and convenient way or wireless connection, but if it is a relatively long-term non-smart TV, you can only choose plug-and-play cable connection, but I also recommend that you use the TV box, the price is even higher than Those switch cables are also cheap, and wireless multi-screen interaction is much more convenient.
