A Novel Current-Balancing Method for Paralleled MOSFETs in High-Current Solid-State Switch Applications: Paralleling a Large Number of Semiconductor Devices by Adding Inductances in Series

In this article, a novel method is proposed to parallel individual power semiconductor devices in solidstate switch application, and it may be extended to any other low/medium switching frequency application. The proposed method does not limit the number of devices in parallel, and, thus, very high currents can be achieved by paralleling smaller semiconductor devices. In addition, it is implemented using low-cost components and does not require complicated realtime measurements/processes to balance the dynamic currents among devices.
