Injection transformer range
Introduction
When testing the transfer function of a control loop, a ‘disturbance signal’ from which frequency response analysis can be made is ‘injected’ into the loop.
In order to ensure that the test system does not change the transfer function results, it is important that the signal generator providing the disturbance signal is isolated from the circuit being tested.
This isolation can be achieved using a transformer or active isolation circuit that meets thefrequency range and voltage isolation requirements of a specific test environment.
