Arc Power Supply with Profibus Communication Protocol for PVD Cathodic Arc Deposition
This arc power supply is a new generation of high-quality ion plated DC multi arc power supply designed and developed for the hydrogen fuel cell bipolar plate industry.
The arc power source operates in high-frequency conversion mode and outputs DC. The control circuit adopts a circuit structure controlled by DSP and proportional integral derivative control technology (PID), and the main circuit topology adopts PFC+IGBT full bridge architecture. Compared with MOSFET power supply, the stability is improved by 20 times and the control accuracy is improved by 5 times. Steady current accuracy ≤ 0.5%. The arc coating power supply is equipped with load compensation circuit, small current stable arc circuit, and protection circuit for over temperature and over current, as well as a touch screen convenient operation panel, analog and RS485 communication interface. Good load characteristics, 100% load duration.
This power supply is also suitable for inline plating system. This unit is equipped with an anti electromagnetic interference (EMI) circuit, and the input and output signals, control signals, etc. are all in fully isolated mode to prevent electromagnetic interference from causing faults in the arc power supply and other electrical equipment.
This power supply structure is reasonable, simple for both of remote control and local control, and straightforward display.
It has an unique air duct design with intelligent air cooling system, silent and energy-saving. Its core greatly improves the computing speed, with fast speed, high accuracy, agile arc dynamic response, smoother output current characteristics, soft and non intense arc, and undistorted waveform.
