【Abstract】 Some problems needed to be solved in traditional plating power supply.The design of adjustable_voltage and frequency bipolarity pulse plating power supply are introduced.The DSP device TMS320F240 is used in the control system for real time control in power converters. And the silicon controlled rectifiers(SCRs) and IGBT chopper converters are used in the main circuit.The experimental results verify that among anodic oxidation to generate porcelain on metals and their alloy surface, waveform transformation of voltage and tuning for wide pulse parameters are well realized.更多还原
