Abstract: A new current-sharing interface circuit which connects paralleled power modules to a common load in a parallel power module system is proposed in this paper. Novel current-sensing and current-sharing techniques are applied. In the interface circuit the output currents of the paralleled power modules are sensed by measuring the inductor voltage drops and shared under a hysteresis current control based on the minimum current. Not only good current-sharing performance but also low power dissipation with low cost can be achieved when the parallel power module system utilizes the proposed interface circuit. A prototype of the current-sharing interface circuit for three paralleled power modules is implemented. The experimental results are in good agreement with the theoretical analyses.
