The conventional circuit symbol for a simple push-pull transformer is shown below. The dots above each winding are used to indicate the sense of mutual inductance and the winding phase. In practical ...

This gate-drive transformer (GDT)circuit allows the drive signal to the MOSFET to range from 50% down to 0%, while still offering a fast turn-off that cannot be accomplished with a simple load ...

Figure 1 Two transistors and an easily assembled transformer drive a white LED from a single 1.5V battery. During the time it takes to charge T 1 's primary inductance, resistor R 1 and T 1 's added ...

Inductors and transformers serve key roles in switch-mode power supplies. Ensuring they perform as expected requires thorough in-circuit measurements performed under operating conditions. Here’s ...
