How current transformers and power transformers differ in connection, core flux, design goals and failure modes, including why a CT secondary must stay closed.
The inductors and chokes in a battery energy storage converter: bidirectional DC-DC stages, ripple control, grid filters and how to specify them.
When does a standard inductor or transformer do the job, and when does a custom design earn its place? A position-by-position way to decide.
An LCR meter gives a number in seconds, but only the right settings make that number meaningful. Follow this bench procedure to get readings…
A practical five-step method for designing a mains or DC input EMI filter, from the first LISN measurement to damping, layout and final verification.
EE, EF, ETD, EER, PQ, RM, UU or toroid? A practical comparison of ferrite core shapes covering power handling, shielding, leakage, winding effort and…
How to select inductors and transformers for LED lighting drivers: ripple, saturation, shielding, EMI filtering and temperature inside the luminaire.
Where inductors, chokes and transformers sit in data centre power conversion, how their requirements are changing, and what to define when requesting custom parts.
Inductor datasheets look simple, but the test conditions behind each number decide whether a part suits your circuit. Here is how to interpret every…
How to filter EMI in LED drivers where space, heat, power factor, dimming and the absence of an earth connection all constrain the design.
