Description

Technical Field

[0001] The utility model relates to the technical field of microwave power supply devices, in particular to a microwave power supply module isolation parallel device. Background Art

[0002] With the rapid development of microwave technology, microwave power supply is an important component of microwave system, and its performance stability and reliability are crucial to the operation of the whole system. In microwave system, in order to meet the requirements of high power, high efficiency and high reliability, it is often necessary to use multiple microwave power supply modules in parallel. However, the traditional parallel method has some difficult-to-solve problems, which makes the effect of parallel use unsatisfactory.

[0003] First, the parallel connection between microwave power supply modules may lead to uneven current distribution. When connected in parallel, due to differences in the internal parameters of each module (such as impedance, capacitance, etc.), the current is unevenly distributed between the modules, which may cause some modules to overload and thus shorten their service life or damage them.

[0004] Secondly, the mutual influence between microwave power supply modules may cause output instability. When used in parallel, the output fluctuation of one module may be transmitted to other modules through the parallel connection, resulting in unstable output of the entire system and affecting the performance of the system.

[0005] In order to avoid the above problems, the microwave power supplies currently used all use module isolation parallel connection to achieve efficient and stable transmission operation. However, with the increase of electronic devices inside the isolation parallel device, most of the isolation parallel devices are closed structures on the outside, which do not have a good heat dissipation effect, which will affect the stable operation of the internal electronic devices and bring inconvenience to the users. In view of this, we propose a microwave power supply module isolation parallel device. Utility Model Content
