The AC comparators, Figures 1 and Figure 2, allow you to visually monitor the levels of AC input signals. Previously, for express assessment of the levels of controlled signals, a method of ...

The circuit in Figure 1 provides a low-cost, isolated ac-line monitor that measures ac-line-voltage level and has some other unique capabilities. The analysis of the circuit is straightforward: When ...

Common issues with AC or DC power supply circuits can include no output voltage or current, low output voltage or current, high output voltage or current, and ripple or noise on the output. These ...

Implementing this type of exact and ensured voltage limit to the downstream AC-input components allows the protection designer to minimize the voltage ratings of those components, likely saving costs ...

The above circuit diagram illustrates a simple AC/DC converter: Four general-purpose rectifier diodes are used here to rectify the AC input. The functionality of the transformer is to step down the ...

The in-circuit differential-mode (DM) impedance at the AC input of a motor drive system (MDS) serves as a key parameter to evaluate and estimate the DM electromagnetic interference (EMI) noise caused ...

This paper presents a novel driver circuit with input current shaping (ICS) and soft-switching features, which consists of a front AC-DC full-wave bridge rectifier and a rear DC-AC circuit combining a ...
