  • Adjustable AC/DC conversion topology to regulate an isolated DC load with low AC ripple
    Patent number: 10947636
    Abstract: Electroplating and painting systems, methods and power converters are disclosed to provide regulated individual DC output signals to anode structures distributed in a plating solution in a tank to promote formation of plating material on a workpiece using a PWM inverter to generate a first AC signal, a sinewave filter to provide a filtered AC signal, a multiphase isolation transformer to provide a plurality of isolated AC signals, a multi-pulse diode bridge rectifier to provide a DC rectifier output signal, an output filter to provide a filtered DC rectifier output signal, and a blocking diode to provide the filtered DC rectifier output signal to the corresponding tank anode structure.
    Type: Grant
