A high - frequency rectifier is a rectifying device, simply speaking, a high - frequency switching power supply device that converts alternating current (AC) into direct current (DC). It has two main functions: first, converting AC into DC, which is then supplied after filtering. A high - frequency rectifier is a rectifying device, simply speaking, a high - frequency switching power supply device that converts AC into DC.
This product uses high - quality imported IGBT as the main power component, nanocrystalline soft magnetic alloy as the main transformer core, adopts multi - loop control technology for the main control system, and takes measures to prevent salt - fog and acidification in its structure.
A high - frequency rectifier is an electronic circuit that converts an AC signal into a DC signal. Its characteristics are as follows:
- High Efficiency: High - frequency rectifiers use components such as high - frequency transformers and capacitors, enabling efficient power conversion, so they are suitable for applications that require high efficiency.
- High Frequency: High - frequency rectifiers can operate at high frequencies, allowing for a small - sized and lightweight design.
- High Power Density: Due to their small size and high efficiency, high - frequency rectifiers can achieve high power density, giving them an advantage in applications that require high power density.
- Low Noise: The output voltage of high - frequency rectifiers has a small ripple, making them suitable for applications that require low noise.
- Easy Adjustment: High - frequency rectifiers can adjust the output voltage by changing the capacitance value of the capacitor, so they have good adjustability.
Application Characteristics
- Reduces porosity. The formation rate of crystal nuclei is greater than the growth rate, promoting the refinement of crystal nuclei.
- Improves adhesion. Breaks through the passive film, which is beneficial for a firm bond between the substrate and the coating.
- Improves covering and dispersing abilities. The high negative potential of the cathode enables deposition in passivated areas during ordinary electroplating, alleviating defects such as "burning" and "dendritic" deposition caused by excessive consumption of deposition ions at the protruding parts of complex - shaped parts. For a coating with a given characteristic (such as color, porosity - free, etc.), the thickness can be reduced to 1/3 - 1/2 of the original, saving raw materials.
- Reduces the internal stress of the coating, improves lattice defects, impurities, voids, nodules, etc., and easily obtains a crack - free coating, reducing the use of additives.
- Facilitates the acquisition of alloy coatings with stable compositions.
- Improves anode dissolution, eliminating the need for anode activators.
- Improves the mechanical and physical properties of the coating, such as increasing density, reducing surface and volume resistance, improving toughness, wear resistance, and corrosion resistance, and also allowing control of the coating hardness.
Traditional electroplating methods for suppressing side effects, improving current distribution, regulating liquid - phase mass transfer processes, and controlling crystal orientation have become ineffective. Research on complexing agents and additives has become the main direction of electroplating process research. Nanometer - scale switching power supplies have solved the defects of traditional high - frequency rectifiers.
