For small transformers, the main problem is that the insulation (the PCB laminate) takes up more volume than the conductors. I think he said at one point that he was using 0.4mm PCB laminate, so ...

The PCB Regulations (SOR/2008-273) came into force on September 5, 2008. ... Current transformers, potential transformers, circuit breakers, reclosers and bushings that are located at an electrical ...

Designed to save pcb space, while simplifying layouts and reducing component mounting requirements, device provides fully tunable magnetizing and leakage inductance with minimal parasitic variation.

After a PCB-contaminated electrical transformer was struck last year, requiring a cleanup that cost more than $350,000, the town’s electric division embarked on a mission.The division sought to ...

Magnetic cores have been used in transformers for over a century. In this paper, the authors present a fundamental concept of using "coreless" printed-circuit-board (PCB) transformers. With the aid of ...
