Shenzhen Rongdaxin electroplating hard chromium high frequency electroplating power supply mainly consists of the following parts:
1, the main circuit, from the AC power grid input, DC output of the whole process, including:
Input filter: Its role is to filter the clutter existing in the power grid, but also hinder the clutter generated by the machine to feedback to the public power grid.
Rectifier and filter: the AC power supply of the grid is directly rectified into a smoother direct current for the next level of conversion.
Inverter: the direct current after rectification into high-frequency alternating current, which is the core part of the high-frequency switching power supply, the higher the frequency, the smaller the ratio of volume, weight and output power.
Output rectification and filtering: Provide stable and reliable DC power supply according to load requirements.
2. Control circuit
On the one hand, it is taken out from the output end, compared with the set standard, and then the inverter is controlled to change its frequency or pulse width to achieve output stability; The other machine, according to the data provided by the test circuit and identified by the protection circuit, provides the control circuit to carry out various protection measures for the rectifier.
3. Detection circuit
The pendant provides protection for various parameters in operation in the circuit, and also provides various display instrument data.
4. Auxiliary power supply
Power supply for different requirements of all single circuits.
