Title: Light receiving section for photocoupling element
Inventor: MURAYAMA ATSUSHI
IPC: H03K17/13
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To realize a light receiving section of the photocoupling element whose zero cross voltage is optionally changed after manufacture with a simple configuration. SOLUTION: Both terminals 4a, 4b are closed or open by a photo thyristor 21 depending whether or not a light emitting section 3 is lighted. When a voltage Vx between both the terminals reaches a zero cross voltage Vox, a gate voltage of a field effect transistor Q13 reaches a prescribed threshold voltage. As a result, an optical current Isc1 produced in the photo thyristor 21 is absorbed and the photo thyristor 21 cuts off both the terminals 4a, 4b independently whichever the light emitting section 3 is lighted. When an input current IF is changed at lighting, a light receiving amount of a CdS cell 32, and a voltage division ratio of a zero cross voltage adjustment section 23, that is, a ratio of the gate voltage of the field effect transistor Q13 and the voltage Vx between both the terminals is changed.  Thus, the zero cross voltage Vox is adjusted to be a desired value depending on the input current IF.
