Abstract
A 6.5 V/50 kA high-frequency switching power supply (HSPS) system composed of 10 power modules is developed to meetthe requirements of copper-foil electrolysis. The power module is composed of a two-leg pulse width modulation (PWM)rectifier and a DC/DC converter. The DC/DC converter adopts two full-wave rectifiers in parallel to enhance the output. For thetwo-leg PWM rectifier, the ripple of the DC-link voltage is derived. A composite control method with a ripple filter is thenproposed to effectively improve the performance of the rectifier. To meet the process demand of copper-foil electrolysis, thevirtual impedance-based current-sharing control method with load current full feedforward is proposed for n-parallel DC/DCconverters. The roles of load current feedforward and virtual impedance are analyzed, and the current-sharing control model ofthe HSPS system is derived. Virtual impedance is used to adjust the current-sharing impedance without changing the equivalentoutput impedance, which can effectively reduce current-sharing errors. Finally, simulation and experimental results verify thestructure and control method.
