A Bipolar Current Actuated Gate Driver for JFET Based Bidirectional Scalable Solid-State Circuit Breakers

Abstract

The invention can improve high speed bi-directional fault protection in a broad range of power conversion and distribution systems such as hybrid vehicle drives and renewable energy systems. This gate driver enables bidirectional over-current protection to prevent system damage and destructive failure. Key features/benefits include: Controls normally ON scalable bidirectional solid-state circuit breakers (BDSSCBs) Fast acting: actuates in approximately 2 s Provides over-current protection, automatically compensating for temperature changes Responds to external sensor triggering, in addition to internal triggering Ultra low power consumption in the BDSSCB ON-state Has been demonstrated using very normally-ON 1.2-kV, 10-A silicon carbide (SiC)JFETs A robust addition to a battery pack providing protection during charge, discharge, and servicing.
