摘要
针对传统FF(Field Foundation)总线电源调节器体积庞大、非常笨重,不利于提高产品集成度,同时其参数一致性差,且存在由于体积太大而难以实现FF电源调节器冗余方案等技术难点,文章介绍了一种基于运算放大器的有源调节器电路,可以有效地解决上述难题,同时也降低了成本,打破了对电感厂商的依赖,提高了总线通信的性能。另外,针对非平衡的有源调节器电路的抗干扰能力较弱特点,通过对有源调节器抗干扰分析和创建一种新的平衡结构方法,使其达到与传统平衡结构相同的抗干扰能力,并通过了仿真验证。
For traditional FF fieldbus power conditioner is big, and heavy, is not conducive to improve the product integration, consistency and its parameters is poor, as the volume is too big and difficult to realize FF power conditioner redundancy scheme and other technical difficulties, the paper introduces a kind of active regulator circuit based on operational amplifier, can effectively solve the above problem, but also reduces the cost, to break the dependence on inductance manufacturer, to improve the performance of the bus communication. In addition, in view of the unbalanced characteristics of weak anti-interference ability of active regulator circuit, by analyzing the active controller anti-interference and the creation of a new equilibrium structure method, to the same as the traditional balance structure of anti-interference ability, and through the simulation.
