Abstract: This paper proposes a current-sharing (CS) circuit for parallel power modules. The interface circuit enables the outputs of independent and nonidentical power modules to equally share the load current in a fault-tolerant oring-connection power supply system. No CS interconnections among the power modules are required. In the proposed interface circuit, the output currents of the parallel power modules are sensed by measuring the inductor voltage drops and controlled in a hysteresis manner. A practical CS interface circuit is implemented. The experimental results are in good agreement with the theoretical analyses.
