Microwave application system of remotely monitored LCC resonant converter

Abstract

The invention relates to a microwave application system of a remotely monitored LCC resonant converter, and belongs to the technical field of microwave application devices. The microwave application system comprises mainly an input rectifier filter circuit, a half-bridge LLC filament power supply circuit, an LCC resonant converter main circuit, RS-485 communication circuits, and the like; through two RS-485 buses, the microwave application system on the one hand receives data and commands from the host computer and executes, on the other hand reads various electric parameters measured by the electrical parameter measurement module, to achieve the remote control; using the half-bridge LLC filament power supply circuit, the microwave application system achieves the direct current power supply of the filament. The microwave application system adopts the Internet of things technology using the microprocessor as the core, to achieve the remote monitoring of the microwave application devices, the operator can not only be far away from the microwave, but also simultaneously control more than one microwave application devices; through the mechanism of combining the LLC soft-switch technology with the synchronous rectification technology, the electronics issued by the magnetron cathode are more uniform, and the system stability of the microwave application devices is enhanced.

Description

technical field [0001] The invention relates to a microwave application system for remote monitoring of an LCC resonant converter, belonging to the technical field of microwave applicator equipment. Background technique [0002] Microwave applicators are mainly used in material synthesis, sintering, heating, etc., especially the synthesis and sintering of materials, which have particularly high requirements for temperature curves. Therefore, microwave applicators not only need a friendly human-computer interaction environment, but also need a temperature-based stable closed-loop control process. In addition, the equipment should also have a series of characteristics such as miniaturization, high efficiency, and environmental protection. [0003] The cathode of the magnetron is the emitter of electrons and an integral part of the interaction space. The performance of the cathode has a great influence on the working characteristics and life of the tube, and it is regarded as...

AI Technical Summary

Problems solved by technology

However, the traditional magnetron cathode is powered by AC 3.3V / 10A power supply, which has a great impact on the stability and life of the tube.

[0004] Existing microwave applications can be operated locally, but cannot be controlled remotely, which is not convenient for centralized control of the system, data processing and storage, and export of reports, etc.
