实际应用发现,使用传统的非隔离稳压电源供电的系统,常常受到各种干扰,如浪涌、静电等,导致电路不能正常工作或系统不稳定、数据传输的误码率高,甚至出现故障损坏等。
为提高系统的稳定性及可靠性,建议客户在设计工控类产品的前级电源时,尽量选择带隔离的电源模块;在工作环境较好,要求不高的场合,系统前级电源可选择非隔离的电源模块。
(2)方案推荐一:采用带隔离的宽压输入电源模块宽电压输入系列DC-DC模块,转换效率高,高低温度特性好,带容性负载能力强,具有完善的保护功能,可持续短路,标准引脚方式,UL94-V0阻燃封装,自然冷却,无需外加散热片,无需外加元件可直接使用,可直接焊在PCB板上。电路结构为闭环反馈系统,内部框图如图 1.1所示。特别适合于DC输入的系统前级供电
不需要隔离措施,可选择宽压输入非隔离输出的电源模块,其内部框图如图1.3所示。使用时,根据实际需要,可在模块的输入端安装丝、瞬态保护二极管和防止输入电压反接的保护二极管,可以有效防止电路反接、输入瞬态过压和因模块失效造成输入端的短路。建议丝选用熔断时间小于10ms、额定电流大于2倍模块输入电流的慢速丝。
