Problems solved by technology
[0003] The existing high-frequency rectification equipment generally adopts the integrated setting of the whole machine, and the output of the whole machine is realized by controlling each module through the main control module. Since each module set in this kind of high-frequency rectification equipment is fixed, its output power is constant. , there are certain limitations
In addition, due to the integrated setting of the whole machine, when a module in the device fails, the whole device must be shut down before the whole machine can be repaired or replaced, which is cumbersome to operate and delays the load. operation, affecting its work efficiency

The invention belongs to the high frequency switch power supply technology field and especially relates to high frequency rectification equipment. The equipment comprises a cabinet body, a main control module arranged in the cabinet body and a plurality of high-frequency rectification devices which are connected in parallel with each other. The plurality of high-frequency rectification devices are electrically connected to the main control module respectively. An input terminal of each high-frequency rectification device is connected to an alternating current power supply respectively and an output terminal of each high-frequency rectification device is connected to a load respectively. A control switch is arranged between each input terminal and the alternating current power supply. The number of the high-frequency rectification devices can be selectively increased or reduced according to a power requirement of the load. The high-frequency rectification devices are arranged in the cabinet body from top to bottom. Each high-frequency rectification device is movably connected with an inner wall of the cabinet body through a movable mechanism respectively. The high-frequency rectification devices can be moved inwardly when being pushed inwardly and the high-frequency rectification devices can be moved outwardly when being pulled outwardly. In the invention, according to a need of the load, different power can be output; and when one high-frequency rectification device has a fault, work of the other high-frequency rectification devices is not influenced.
Description
technical field [0001] The invention belongs to the technical field of high-frequency switching power supplies, in particular to a high-frequency rectifying device. Background technique [0002] With the development of society and the advancement of science and technology, high-frequency switching power supplies are widely used in industrial equipment, power systems, transportation, military equipment and other fields. DC power is supplied to the load. [0003] The existing high-frequency rectification equipment generally adopts the integrated setting of the whole machine, and the output of the whole machine is realized by controlling each module through the main control module. Since each module set in this kind of high-frequency rectification equipment is fixed, its output power is constant. , there are certain limitations. In addition, due to the integrated setting of the whole machine, when a module in the device fails, the whole device must be shut down before the who...
