Abstract
In order to meet the requirements of electrolytic copper-foil, a 6.5V/50kA power supply system composed of ten power modules is developed. The power module is composed of two-leg PWM rectifier and dc/dc converter, and dc/dc converter adopts two full-wave rectifiers in parallel to enhance the output ability. In order to meet the process requirements of electrolytic copper-foil, a virtual impedance based current-sharing control method with load current full feedforward is proposed for n-parallel dc/dc converters. The virtual impedance is used to adjust the current-sharing impedance without changing the equivalent output impedance of converter. It can effectively improve the output performance and eliminate the current-sharing errors. Finally, simulation and industrial application results have verified the structure and control method.
