A high frequency transformer is a key component when designing isolated switching mode power supplies (SMPS). Leakage inductance is essential in the control of many design parameters including efficiency, maximum voltage rating for switching elements and EMI when it comes to designs using customized transformers. Accurate measurement of this parasitic element is mandatory. The R&S®LCX LCR meter is ideal for this challenging measurement task.

This document is divided in two parts and starts with an introduction in AC-DC conversion principles in general. It will present the most common circuits used for different power levels. The switching mode power supply (SMPS) converter will be the main focus as they are used everywhere in the electronics. Especially the flyback converter design in different flavors are highlighted. Nevertheless, all measurements are also applicable for other SMPS converter designs operating at higher power levels.In the second part of this document, most relevant testing methods and procedures of an AC-DC converter are highlighted. For each testing section, a fundamental part will be upfront discussed and it is followed by a presentation of a suitable measurement method. In this second part, the device under test (DUT) is considered as black box device and thus the structure is similar. Therefore, the testing parts consists of methods related to input tests, output tests and a combination of both like efficiency. Of course, some test performed at the output of the converter are also relevant for DC-DC converter, e.g. the validation of the output ripple.

An offline AC/DC switching converter has no separate bias power supply that provides power to the control integrated circuit itself. Here, an auxiliary primary winding and discrete components are added to supply power to the control circuit. Verifying this circuitry is essential and requires accurate and detailed signal level and timing measurements. The startup sequence takes a long time, which needs to be taken into consideration in the measurement and requires an instrument with sufficient memory.
