Title
(EN) TERMINAL CIRCUIT IN INVERTER
(KO) 인버터의 단자 회로
Abstract
(EN)
Disclosed is a terminal circuit in an inverter. The circuit according to the present invention includes: a photocoupler which electrically insulates an input-output signal, receives an open collector output signal or a pulse output signal from a first port as an input, and outputs the received output signal to a second port as a first output; a transistor whose base (B) is connected to a second output of the photocoupler; and a bias resistance is connected to the base (B) and an emitter (E) of the transistor.
