Application for high frequency DC power supply

The high-frequency DC power supply is based on high-quality imported IGBTs as the main power device, and ultra-microcrystalline (also known as 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. This kind of power supply has become an updated product of SCR power supply due to its small size, light weight, high efficiency and high reliability.

They are widely used in large power plants, hydropower plants, ultra-high voltage substations, unattended substations as control, signal, protection, automatic reclosing operation, emergency lighting, DC oil pump, experiment, oxidation, electrolysis, zinc plating, nickel plating, tin plating , Chrome plating, photoelectric, smelting, chemical conversion, corrosion and other precision surface treatment places. In anodizing, vacuum coating, electrolysis, electrophoresis, water treatment, electronic product aging, electric heating, electrochemistry, etc., it is also favored by more and more users. Especially in the electroplating and electrolysis industries, it has become the first choice for many customers.

Main features:

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. The circuit forms are flexible and diverse, and can be divided into width-adjusted, frequency-modulated, single-ended and double-ended. High-frequency DC power supplies suitable for application scenarios can be designed according to the actual situation.

3. Good energy saving effect:

Switching power supply adopts high frequency transformer, the conversion efficiency is greatly improved. Under normal circumstances, the efficiency is higher than that of SCR equipment by more than 10%, and when the load rate is below 70%, the efficiency is higher than that of SCR equipment by more than 30%.

4. 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 switching power supply has high working efficiency, so the control accuracy is high, which is beneficial to improve product quality.

5. The output wave form 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 user process requirements. This has a strong effect on improving work site efficiency and improving the quality of processed products.
