新型线性光电隔离电路的设计
资料介绍
先从线性隔离电路和线性隔离模块的现状出发,从内部原理上分析其各自的优缺点,然后引进了一种新型的线性光电隔离电路。先从理论的角度分析此电路的优缺点,以及是否能够有效地弥补常用线性隔离电路的缺点,之后从理论上计算与此电路性能相关的参数和指标。然后根据理论计算,建立相应的测试系统来测试该电路的性能。结果表明,它可以广泛应用于系统电源少、对信号输入要求比较低的场合,尤其是便携式产品上。
Although many usual circuits of optical-coupler can translate analog signal with high precision,it needs special condition to power supplies and other components.A new linear isolating circuit of optical-coupler is introduced to overcome the weakness.It only needs general optical-coupler and a single power channel,but can accurately translate analog signal isolated.Then the test system is setup for this circuit.And necessary test items are finished to evaluate the performance of this circuit.At last,the advantage and disadvantage are summarized.
