Microarc Oxidation Power Supply Based on Automatically Control

摘要：

An automatically controlled power supply for microarc oxidation (MAO) is introduced in this paper. Electronic voltage regulator and insulated gate bipolar transistor (IGBT) are applied in the power supply. The power supply can output variety of discharge waveform such as constant voltage, voltage pulse, symmetry alternating pulse and asymmetry alternate pulse. Number of discharge pulse from anode or cathode in a period is adjustable. Meanwhile, the power supply can work in the mode of constant voltage/current/power. It can also communicate with computer through USB port. Furthermore, in this mode, computer software monitors and records the operating parameters such as peak voltage and current of discharge. The experimental results show that whenever it accesses resistance or the MAO treatment tank. The power supply outputs a stable waveform with very low pulse edge jitter. It fully satisfies the requirements of MAO process.
