在全球能源持续紧张的情况下,我们国家也积极推进节能减排的工作,从国家的“十一五”规划到“十二五”规划中都在积极的推进节能减排,节能技术在各个领域和行业中都得到了创新和发展。本文对电力用高频开关电源节能技术专项研究,本节能技术方案,通过监控模块智能管理系统软件的升级,科学地对系统在线实际冗余整流模块实施软关断控制,保持效率转换最佳区域,达到节能目的,从而降低了电源系统的能耗。 In the context of continued global energy shortage, our country is also actively promoting energy conservation and emission reduction. We are actively promoting energy conservation and emission reduction from the national “Eleventh Five-Year Plan” to the “Twelfth Five-Year Plan” Energy-saving technologies have been innovated and developed in various fields and industries. In this paper, a special study of energy-saving technologies for high-frequency switching power supply for power and energy saving technologies has been implemented. By software upgrade of the intelligent management system of monitoring module, the system can implement soft-off control to the actual redundant rectifier module of the system online and keep the best area of ​​efficiency conversion , To save energy, thereby reducing the power consumption of the power system.
