Abstract

See full text

An electrical safety system comprises a main safety device including a N-type transistor and an auxiliary safety device including a P-type transistor, alternately activated under command of a controller. The N-type transistor and the P-type transistor have the function of overcurrent protection, respectively in a first operating mode and in a second operating mode. The auxiliary safety device includes a passive component, connected in series with the P-type transistor, for providing a voltage drop when a current passes through the passive component, and a driving circuit for turning off the P-type transistor under control of the voltage drop exceeding a first threshold, in the second operating mode.
