Abstract:
An optical-controlled driving circuit adapts to a high utility power environment with high voltages, large currents and severe surges, and includes an optical-controlled switch circuit, an SCR with optical-controlled driver and a main circuit. The optical-controlled switch circuit includes an optical-controlled component and a first switching transistor that are connected in serial. The SCR with optical-controlled driver includes at least two switching transistors that are connected in serial and a plurality of diodes, and is coupled to the main circuit. The optical-controlled driving circuit generates a driving current according to the voltage of a utility power. When the optical-controlled driving circuit is used in a DC converter using an SCR as a switch element, the optical-controlled driving circuit helps to increase the operation efficiency when the DC converter works under a light load.
