Abstract:

Aiming at the faults problems, which may occur in operation of switch type excitation system, based on the fundamental of PSVR100 excitation

regulator made in Guodian Nanjing Automation Company Limited, the reliability design method of the regulator, the main circuit and the driving circuit was

put forward. The test results show that the reliability of switch type excitation system can be increased effectively by adopting this reliability design

technology. 
