Special Pulse Power Supply

A development and updating solution for the controlling system of a high-power special pulse power supply as used in the process of potting in magnesium and aluminium ect light-alloy surface is discussed. The power supply controller adopts INTEL 16 bit signal chip employing the core of controller, full-bridge controlled rectifying and reversing technique in its main circuit, pulse width modulation technique is adopted in controlling circuit. The high-power special pulse power supply has been accomplished as well as two polarities asymmetry pulse output. The power supply can operate under the statement of constant current and constant voltage.RS-485 bus is adopted in the pulse power supply system accomplishing the chain communications of between power supply and PC. With respect to the complexity of the processes and load model, a fuzzy controlling algorithm is employed, gaining fairly good constant-current control performance.
