Inductive reactance is the resistance to current flow in an AC circuit, due to the effects of inductors in the circuit. Inductors are coils of wire, especially those that are wound on an iron core.

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

The MOSFET power switch is commonly the most vulnerable part of a new switched-mode high-power circuit. One threat for this device is exceeding the value of the maximum allowed pulse current. You ...

This article looks at the equivalent circuits for quasi-resonant cookers and coil characteristics relating to the various pan materials used in these implements.

With the modified circuit, the turn-off time is reduced by increasing the clamp voltage. The circuit uses the same configuration of N-channel power MOSFETs for both the low-side conduction and the ...
