Transformer Rectifier Assemblies
-
Transformer rectifier assemblies are very useful in OEM applications when unregulated DC output is required. Input power can be single-phase or three phases. With single-phase input power, the output ripple is 50%. With three-phase input power, the output ripple is 5%. A 5% output ripple is a clear advantage. Hence, transformer rectifier assemblies with three-phase input power are more popular. Circuit breakers, fuses, voltmeters, and ammeters can be added per customer requirements. The assemblies can be an open frame or inside an indoor enclosure.

Injection Transformer
J2100A
-
The injection transformer is presently the prevalent method for connecting the network analyzer to the circuit being tested, and is primarily used for control loop stability measurements. The goal of the transformer is to inject a signal into the control loop being measured, without impacting the performance of the loop. In order to accomplish this to a reasonable degree, The transformer is isolated and therefore is capable of floating on a high voltage, such as a Power Factor Corrector (PFC), which is often close to 400VDC. Measuring voltages that exceed the voltage rating of the FRA inputs require attenuation probes.

AC Test Transformer
-
Shanghai Guantu Technology Co., Ltd.
How the AC test transformer prevents the overvoltage generated by the frequency conversion series resonance test device is a relatively simple problem, but the overvoltage caused by voltage fluctuation is difficult to appear when the overvoltage protection is set. Generally, the overvoltage of the frequency conversion series resonance test device will appear in the frequency sweep stage of the instrument, that is, in the process of finding the resonance point. Those who have used it know that in the process of finding the resonance point of the frequency conversion series resonance test device, the voltage and frequency have a parabola-like linear relationship. By default, the system finds the high voltage, that is, the apex of the parabola as the resonance point.
