    Orient Intelligent IGBT Driver Optocoupler Products Introduction

    In the electronic power system, the IGBT drive circuit is a very crucial component. As the interface circuit between the module and the single-chip microcomputer, it needs to convert the signal from the single-chip microcomputer into a drive signal with sufficient power to ensure the safe on and off of the IGBT and provide electrical isolation between the two. In order to ensure that the IGBT is correctly and effectively protected when a system failure occurs, a separate protection circuit needs to be designed for the conventional IGBT drive circuit.

    OR-MOC30XX Thyristor Optocoupler Product Introduction

    Thyristor photocouplers can be isolated for AC load control, provided the load is relatively small (about 50 mA or less). For larger currents (up to a few amps), a SCR photocoupler is combined with a high-power SCR for AC load control. The following diagram shows the basic circuit configuration. Rs and Cs are elements of the buffer circuit that prevent the thyristor photocoupler switch failure by shielding noise, while the varistor absorbs any surge voltage from the power line.
