A pulse power supply is a power supply that uses pulse modulation to change the width of the output pulse by periodically adjusting the duty cycle and changing the width of the output pulse. Micro-arc oxidation pulse power supply is a new type of pulse power supply, which adopts micro-arc oxidation technology and can be used for anti-corrosion treatment of various metal surfaces.

The characteristics of micro-arc oxidation pulse power supply are its advantages of high power density, high frequency, high efficiency, high reliability and long life. Compared with the traditional pulse power supply, the micro arc oxidation pulse power supply is smaller in size, lighter in weight, and has higher accuracy in output pulse, which can meet the needs of various high-precision applications.

The circuit structure of micro-arc oxidation pulse power supply mainly includes rectifier circuit, filter circuit, inverter circuit and control system. The rectifier circuit converts the alternating current into direct current, and the filter circuit filters out the alternating current component of the direct current to obtain pure direct current. The inverter circuit converts direct current into high-frequency alternating current, and the control system controls and regulates the entire circuit.

In a micro-arc oxidation pulse power supply, the width and frequency of the output pulses can be adjusted by the control system. By adjusting the width and frequency of the output pulse, it is possible to control the degree of micro-arc oxidation on the metal surface and the thickness of the film layer. At the same time, the micro-arc oxidation pulse power supply also has the functions of over-current protection, over-voltage protection, over-temperature protection, etc., which can ensure the safe operation of the power supply.

The application range of micro-arc oxidation pulse power supply is very wide, and can be used for anti-corrosion treatment of various metal surfaces, such as aluminum, magnesium, titanium, zirconium and other metal materials. At the same time, the micro-arc oxidation pulse power supply can also be used to manufacture a variety of high-performance metal surface coatings, such as cemented carbide, high-speed steel, etc. In addition, micro-arc oxidation pulse power supply can also be used in electroplating, electrolysis, electrochemistry and other fields.

In the practical application of micro-arc oxidation pulse power supply, some problems need to be paid attention to. First of all, the output voltage and current of the power supply need to match the size and material of the workpiece to be processed. Secondly, it is necessary to keep the surface of the workpiece clean and dry during the processing process to avoid affecting the adhesion and quality of the film. Finally, regular maintenance and maintenance of the power supply is required to ensure its normal operation and service life.

In a word, the micro-arc oxidation pulse power supply is a new type of pulse power supply, which has many advantages and a wide range of applications. In the future, with the continuous progress of technology and the continuous improvement of application requirements, micro-arc oxidation pulse power supply will be more widely used and developed.
