High-frequency DC power supply is a kind of DC power supply. Have you summarized the characteristics of high-frequency DC power supply during actual use?
The advantages of high frequency DC power supply are summarized as follows:
High-power DC power supply manufacturer
1. Small size and light weight:
The volume and weight are 1/5-1/10 of the SCR power supply, which is convenient for you to plan, expand, move, maintain and install.
2. Good energy saving effect:
Switching power supply adopts high frequency transformer, the conversion efficiency is greatly improved. Under normal circumstances, the efficiency of SCR equipment is increased by more than 10%, and when the load rate is below 70%, the efficiency of SCR equipment is increased by more than 30%.
3. High output stability:
Due to the fast response speed of the system (microsecond level), it has strong adaptability to network power and load changes, and the output accuracy can be better than 1%. The working efficiency of the switching power supply is high, so the control precision is high, which is beneficial to improve the product quality.
4. The output waveform is easy to modulate:
Due to the high operating frequency, the relative processing cost of output waveform adjustment is relatively low, and the output waveform can be changed more conveniently according to the user's process requirements. This has a strong effect on improving work site efficiency and improving the quality of processed products.
The high-frequency DC power supply is based on high-quality imported IGBTs as the main power device, and ultra-microcrystalline (also called nanocrystalline) soft magnetic alloy material as the main transformer core. The main control system adopts multi-loop control technology, and the structure is salt-proof Fog acidification measures.
The power supply has a reasonable structure and strong reliability. The power supply has become an updated product of the thyristor power supply due to its small size, light weight, high efficiency, and high reliability.
Shenzhen Sanxinda power supply equipment is a professional power supply manufacturer that produces electroplating power supply, electrolysis power supply, oxidation power supply, electrophoresis power supply and surface treatment power supply. The company adheres to the business philosophy of quality-oriented, energy-saving, and environmental protection, and strives to provide users with high-performance, high-efficiency, and high-reliability surface treatment power equipment.
SXD-PWH series high frequency switching power supply is a high frequency switching power supply originally developed and successfully developed by our factory. It has a completely different working principle from the previous power frequency silicon controlled rectifiers. It generates low voltage and large current output through the input high voltage AC rectifier-high voltage filter-high voltage and high frequency regulation-low voltage and high frequency rectification. Its working principle determines that the power supply has higher conversion efficiency and higher current conversion efficiency than the silicon controlled rectifier. Power factor has become the preferred power supply product for many customers. Using this power supply can significantly reduce production costs and improve product quality. Compared with thyristor power supplies, production energy consumption can be reduced by 20%-30%, bringing considerable economic benefits to users . The power supply is small in size and light in weight (water-cooled is smaller than air-cooled), and it is very easy to install and use, which can save valuable production space for users. The main power high frequency transformer of SXD-PWH series high frequency switching power supply adopts imported nano crystal/ultramicro crystal, high permeability material as the magnetic core, which is small in size and high in efficiency.
High-frequency and high-power switching components (IGBT), power drive modules, and three-phase bridge stack are all selected from international famous brands such as Mitsubishi, Fuji, Freetech, Germany, etc. The circuit board components are all selected from famous manufacturers. Our company has developed a unique water-cooled high-frequency electroplating power supply (patent pending), which has better cooling effect, anti-salt spray acidification, increases the service life of the power supply in harsh environments, and has stronger corrosion resistance, which can greatly extend the service life of the power supply. The water discharged from the machine is free of any pollution and can be recycled and reused! To
SXD-PWH series high frequency switching power supply has complete protection functions: input phase loss, undervoltage, overheating, overcurrent, short circuit protection, safe and reliable.
The SXD-SS-SR series high frequency switching power supply has the following advantages compared with the ordinary switching power supply in the same market:
1. The full-bridge phase-shift soft switching control method is adopted to eliminate the switching stress to the greatest extent, and the world's latest full-bridge soft switching control IC is adopted, which has the function of automatically adjusting and setting the trigger pulse sequence parameters to achieve the best IGBT switching time. The IGBT switching loss is minimized, and the IC with its own synchronous rectification drive function is adopted, which simplifies the synchronous rectification drive circuit. Make its work more stable and reliable.
2. Adopt advanced logic interlock control circuit to eliminate pulse false trigger and overcome bridge arm short circuit.
3. It eliminates the magnetic bias problem, mainly in the following two aspects:
(1) The primary transformer of the main transformer uses series blocking capacitors
(2) Add an automatic bias correction circuit
4. Using foreign original imported MOS tubes as secondary side rectifiers, and using advanced and reliable special imported synchronous rectification module technology, the efficiency of this high-frequency switching power supply is about 15% higher than that of similar ordinary rectifying switching power supplies under low voltage and high current conditions.
