The previous tutorials featured resistors in direct current (DC) circuits wherein the voltage and current have been assumed to be of constant polarity, flow and direction. The voltage, current and ...

This course builds on the fundamentals of DC and AC electrical circuit analysis. It provides an introduction to the design and building of analogue electronic systems. The course will cover a blend of ...

Large power supplies that operatefrom ac wall voltage havelarge input-filter capacitors. You mustlimit the inrush current to those capacitors.Otherwise, the supply may tripthe ac circuit breaker, or ...

Calculations of power and energy are relatively straightforward when the subject is strictly dc circuits. The situation is more complex in the ac world, however. Here are the basics of watts and ...

Check out this interesting wideband AC millivoltmeter circuit from 1990. The simple design features 12 ranges, decent accuracy, 200 µV accuracy, and a frequency range from 20 Hz to more than 2 MHz.

Abstract: Single-phase AC-DC power converters face the challenge of twice-grid frequency power ripple (TGFPR) caused by power imbalance, requiring the use of large DC-side capacitors. Active power ...
