Abstract

This paper presents scheme of solid state protection for electrical appliances used in DC home. The comparison between electromechanical circuit breaker and solid state protection device (SSPD) based on various parameters is being discussed in this paper. This paper discusses about how SSPD tripping characteristics are being matched with that of circuit breaker characteristics. The control block diagram has been presented for SSPD circuit depending upon two tripping zones of the circuit breaker which are thermal trip zone and magnetic trip zone. The simulation and the hardware results of the protection circuit are given and they are matching up to a large extent. An optimized heat sink design is discussed, considering the power dissipation during overload and short circuit conditions.
