Learning Magnetics Just Became Fun with Our New TI-PMLK Buck Kit!

Thought learning magnetics was boring? Think again!

Würth Elektronik has partnered with Texas Instruments to offer a new hands-on learning kit. The TI-PMLK Buck Würth Elektronik Edition kit can help you investigate the impact of magnetics on the performance of a switching power supply and help speed up your design.

(And it's fun!)

How the Kit Makes Learning Magnetics More Fun (Or At Least More Interesting)

Inductors and transformers are key components of any DC-DC converter, which are widely used in power management applications. Unfortunately, most universities don't offer courses in the area of power management, especially addressing the challenges associated with design and optimization of power electronics. This is a very important part of any electronic system.

Würth Elektronik has recently collaborated with Texas Instruments and Professor Nicola Femia from the University of Salerno, Italy, to provide students with a hands-on learning kit to help them understand and investigate the impacts of magnetics in a power supply.

The TI-PMLK Buck Würth Elektronik Edition is part of the TI-PMLK (Power Management Lab Kit) series.

Würth Elektronik has committed to "fight" the growing lack of student interest in magnetics by bringing the first learning kit dedicated to the impact of magnetics in a switching power supply.

What’s Included in the Magnetics Learning Kit

This kit is composed of a single board and an experiment book.

The board consists of two independent buck circuits with six different inductors that can be individually selected. The hands-on kit allows the users to investigate the performances of inductors with different core materials, inductance, and size to analyze their impact on the static and dynamic performance of regulators.

As increasingly more applications require designing power management solutions, deepening knowledge and getting practical experience with these components is important in making trade-offs and solving design challenges. Careful selection of these components is needed for optimizing the design.

Each circuit features adjustable operating conditions including a flexible switching frequency (100kHz – 700kHz) to observe its effect on inductors and on switching regulators operating with different inductors.

Both regulators incorporate a passable EMI input filter to analyze the influence of inductors on conducted noise attenuation and to compare the performance of filters with inductors selected according to different design strategies.

Each regulator includes over-voltage, over-current, and polarity reversal protections to prevent damage to the board. Current sense transformers and integrated current shunt monitors on the board allow easy current measurements using standard voltage probes.

In addition to the hardware, an experiment book with structured labs helps you investigate the board by autonomously performing six detailed experiments for steady-state, transient, and dynamic conditions seen in real-world applications.

The magnetics learning kit allows analyzing the inductance of different inductors, investigating inductor saturation and thermal behavior, estimating DC and AC power loss, measuring ripple current and ripple voltage, and observing continuous and discontinuous operation modes and transient response.
