Micro-arc oxidation pulse rectifier is a new type of power equipment used to treat the surface ceramic treatment of light alloys such as aluminum and magnesium, which is mainly composed of main circuit, control circuit, detection circuit and auxiliary power supply.
The core part of the micro-arc oxidation pulse rectifier is the main circuit. The main circuit adopts a three-phase bridge rectifier circuit, and the pulse current with different output parameters can be obtained by changing the conduction angle of the thyristor. Components such as transformers and reactors in the main circuit can reduce the impact of current and improve the stability and reliability of equipment.
The control circuit is a key part of the micro-arc oxidation pulse rectifier. It uses a digital signal processor (DSP) as the control core, which can quickly and accurately detect the output current and voltage, and control the output parameters by adjusting the trigger pulse of the thyristor. The control circuit can also realize functions such as over-current protection, over-voltage protection and phase loss protection to ensure the safe operation of the equipment.
The detection circuit is an important part of the micro-arc oxidation pulse rectifier. It is mainly used to detect the output current and voltage and feed them back into the control circuit to achieve closed-loop control. The detection circuit can also monitor the operating status of the equipment in real time, find abnormal conditions and alarm in time.
The auxiliary power supply is the auxiliary part of the micro-arc oxidation pulse rectifier. It mainly provides a stable and reliable power supply for other components in the device, such as cooling fans, lights, etc.
Micro-arc oxidation pulse rectifier has a wide application prospect in the surface ceramic treatment of light alloys such as aluminum and magnesium. It can improve treatment efficiency, reduce energy consumption, reduce environmental pollution and other aspects have significant advantages.
