Microprocessors and application-specific integrated circuits (ASICs) require low-voltage, high-current power supplies. These supplies usually have very strict requirements on output-voltage deviations ...

Regardless of the system architecture, the circuit design, or the power levels involved, transient load current step testing is a critical aspect of power-system design, test, and verification.

One part that I find myself using somewhat regularly in microcontroller-based experiments is the “USB power bank” that provides USB-standard 5-V DC output and offers some basic protection features.

As part of a power electronics design project involving a 3.6-V dc-dc converter, it became necessary to test and accurately characterize the planar transformer shown in Fig. 1. Transformer operating ...
