PROTECTION POWER INTERFACE

摘要

FIELD: radio engineering. SUBSTANCE: device input receives continuous logical signals, which are subjected to dynamic encoding by oscillator and sent to serial circuit of two high-power transistors by means of controlled logical circuit. Device provides linear self-test by short pulses. Controlled logical circuit outputs continuous test signal in case of detected fault and non-continuous test signal otherwise. EFFECT: increased reliability due to distribution of error signal or automatic switch of controlled actuating mechanism to safe mode. 10 cl, 1 dwgr
