Analogue Optical Coupler Schematic Circuit Diagram

It is sometimes necessary to make an electrically isolated connection in a circuit. An optical is usually the key component in such a situation. In most optocouplers, a single light-emitting diode (transmitter) and a single photodiode (receiver) are optically coupled inside the package. This solution is satisfactory for transferring digital levels (such as the control[…]

Low-drop a.c. switch for 12 V halogen lights

Because of their inertia, power consumption, contact wear, and often size, relays are not really suitable for switching alternating voltages. Moreover, they cannot be used in phase control circuits. Replacing them by triacs may give problems owing to the forward voltage drop across these devices. A much better solution is the use of anti-series-connected SIPMOS transistors.[…]
