TRANSISTORISERAD LIKRIKTARBRYGGA |
摘要 |
A transistorized bridge rectifier circuit with overcurrent protection which can be integrated monolithically is used for joining to a two-wire telephone line to the electronic circuits of a telephone subscriber set connected thereto. The circuit includes a transistorized bridge having a circuit arranged in the manner of a Graetz bridge. Rather than using separate elements for overcurrent protection, the circuit uses the bridge circuit elements themselves as protection elements. Diodes or diode connected transistors are respectively connected between the base and collector of transistors in two arms of the Graetz bridge and the resultant circuit thus provides overcurrent protection without the need of additional protection elements. |
