Enhanced active resonant (EAR) DC circuit breakers (DCCBs) are a novel type of DCCB that use discharge closing switch as interruption medium. A technical limitation switches is the minimum voltage across main gap required for successful triggering. commutation process creating internally proposed, which allows to simplify EAR configuration and reduce its component count. In prototype, implement...

This paper proposes a novel hybrid equalizer circuit (HEC) for battery management system (BMS) to implement the passive HEC (P-HEC), active (A-HEC), or active/passive (AP-HEC) with same architecture. The advantages of an are that it is simple, cost-effective, highly energy efficient, and fail safe. P-HEC can further use cooling fan heater instead conventional resistor as power dissipation eleme...

A new automatic tuning circuit based on synchronous rectification scheme is proposed and functions in the idle periods between the burst-mode transmissions. The proposed CMOS tuning circuit can be fully integrated with the front-end filter. Simulation results employing 0.5μm CMOS technology have verified that the center frequency is automatically tuned to 1.25GHz with 10% process variation pres...
