随着科学技术的快速发展,我国在全国范围内对中波台推广的力度也越来越大,传统的电子管调制功放电路已经不能满足人们的需求,取而代之的是大功率MOSFET场效应管。在日常工作中,人们需要应用较高的功率、电流,长此以往对模块造成的损坏较为常见,这需要相关的技术工作人员了解大功率MOSFET场效应管的设计原理和应用方法来解决存在的诸多问题。文章对大功率MOSFET场效应管在DX中波发射机中的相关应用,旨在为我国的中波发射技术作出贡献。
With the rapid development of science and technology, China has also made more and more efforts to popularize the wave-wave units nationwide. The traditional tube-modulated power amplifier circuit can no longer meet people’s needs and is replaced by a high-power MOSFET field-effect transistor. In daily work, people need to apply higher power, current, damage to the module over the long term is more common, which requires the relevant technical staff to understand the design principles and application methods of high-power MOSFET FET to solve many problems . The article on the high-power MOSFET FET DX transmitter in the relevant applications, to China’s mid-wave launch technology to contribute.
