CDMA is a rising star in the field of wireless communications. It uses frequency division coding technology and has obvious advantages compared with GSM based on time division multiplexing. CDMA can achieve a smooth transition from the existing communication system to the next
Infineon's EconoDUAL 3 module is a 600A / 1200V IGBT. The main typical applications include frequency converters for automatic drive systems, central inverters for photovoltaic voltage systems, and automotive diesel engine drivers (CAV). 30%. This article introduces the mai
In the power amplifier, emt1237 special protection integrated circuit emt1237 is mostly used. Pay attention to some problems when using it, otherwise it may lose its protection due to improper use, and may seriously damage the integrated block (mainly the power supply voltage
The wireless FM audio transponder can modulate the audio signal into a high-frequency signal and receive it with an FM radio within a certain distance. Wireless audio transponders are widely used in wireless headsets, car MP3 transponders, conference broadcasting, building and
Abstract: High-voltage high-power motors have a relatively large impact on the load and the grid when starting. Thyristor series high-voltage soft starters are widely used for their superior starting performance and other advantages. In this paper, through the application of hi
