Voltage equalization control system and method for constant-current remote power supply in optical network

Abstract

The invention discloses a voltage equalization control system and method for a constant-current remote power supply in an optical network. Multiple constant current generating modules are set up. Voltage equalization control can be realized through a control module, so that the output voltages of the constant current generating modules are consistent, and the loads of the constant current generating modules are the same. Because the modules work in a non-full-load state, the service life of constant-current remote power supply equipment can be prolonged by prolonging the service life of a single constant current generating module, so as to ensure the reliable operation of the system. When any constant current generating module fails, the normal operation of the other constant current generating modules will not be affected, and the control module will adjust the output voltages of the normal constant current generating modules for voltage equalization to replace the load originally borne by the faulty module, so as to improve the reliability of the equipment. The application needs for different supply power can be satisfied without developing new equipment. By configuring differentnumbers of constant current generating modules, the application needs of different supply power can be satisfied, and capacity expansion is easy.
