The Xingtongli brand high-frequency electroplating power supply is a specialized surface treatment equipment developed by our company using the latest international high-frequency switching power supply technology. Its primary components are made of high-quality imported materials, ensuring strong stability and low failure rates. It is widely used in various fields such as galvanizing, chrome plating, copper plating, nickel plating, tin plating, gold plating, silver plating, electro-casting, electroplating, anodizing, PCB hole metallization, copper foil, aluminum foil, and more. The performance is excellent, receiving unanimous praise from our valued customers.
1. Operating Principle
The three-phase AC input is rectified through a three-phase rectifier bridge. The output high-voltage DC is transformed by the IGBT full-bridge inverter circuit, converting the high-frequency high-voltage AC pulses into low-voltage high-frequency AC pulses through a transformer. The low-voltage AC pulses are rectified into DC current by a fast recovery diode module to meet the power requirements of the load.
The principle block diagram of the GKD series high-frequency switch electroplating power supply is shown in the diagram below.
2. Operating Modes
To meet the various electroplating process requirements of users, the “Xingtongli” brand high-frequency switch electroplating power supply offers two basic operating modes:
Constant Voltage/Constant Current (CV/CC) Operation:
A. Constant Voltage (CV) Mode: In this mode, the output voltage of the power supply remains constant within a specified range and does not vary with changes in the load, maintaining basic stability. In this mode, the output current of the power supply is uncertain and depends on the size of the load (when the power supply output current exceeds the rated value, the voltage will drop).
B. Constant Current (CC) Mode: In this mode, the output current of the power supply remains constant within a specified range and does not vary with changes in the load, maintaining basic stability. In this mode, the output voltage of the power supply is uncertain and depends on the size of the load (when the power supply output voltage exceeds the rated value, the current no longer remains stable).
Local Control/Remote Control Operation:
A. Local control refers to controlling the power supply output mode through the display and buttons on the power supply panel.
B. Remote control refers to controlling the power supply output mode through the display and buttons on a remote control box.
Analog and Digital Control Ports:
Analog (0-10V or 0-5V) and digital control ports (4-20mA) can be provided according to user requirements.
Intelligent Control:
Intelligent control options are available based on user preferences. Customized PLC+HMI control methods can be provided, as well as PLC+HMI+IPC or PLC+remote communication protocols (such as RS-485, MODBUS, PROFIBUS, CANopen, EtherCAT, PROFINET, etc.) for remote control. The corresponding communication protocols are provided to enable remote control of the power supply.

4. Product Advantages
Fast Transient Response: The adjustment of voltage and current can be completed within an extremely short period of time, and the adjustment accuracy is very high.
High Operating Frequency: After rectification, high-voltage pulses can be converted with minimal loss through a small-volume high-frequency transformer. This results in significant efficiency improvement, saving 30-50% of electricity compared to silicon rectification devices of the same specification and 20-35% compared to controllable silicon rectification devices of the same specification, leading to significant economic benefits.
