Isolated IGBT gate driver requires isolated power supply for safety isolation and level shifting. Unfortunately design of isolated power supply based on standard power control IC is not trivial.

Boundary scan is going crazy. From humble beginnings in 1990 targeted at solving the limited-access problems of traditional board test based on a physical-touch technology such as bed-of-nails and ...

Maybe you should try boundary scan testing now that your continuity buzzer has died. Most engineers are familiar with the theory of boundary scan testing, but what about having actual hands-on ...
