We had a linear amplifier requirement to deliver +30 dBm (1 watt) peak power to a 50 ohm load over a frequency range of 10 kHz to 40 MHz. The approach was to make a push-pull, class-A, transformer ...

Current transformer (CT) saturation presents a critical challenge in the realm of power system protection and automation. Under fault conditions, the magnetic core of a CT may become saturated, ...

The third edition of IEC 61000-4-3, published in 2006, has mandated changes in some key areas that may require the replacement of your radiated immunity test amplifier. Along with extending the test ...

Digital predistortion is an approach to amplifier linearization that permits the efficiency of the multi-carrier amplifier to be dramatically increased. The principle of predistortion is intrinsically ...

Single-transistor forward converters are popular in higher-power isolated power supplies because they feature low parts count and component stress. On the downside, careful attention must be given to ...

Low voltage amplifiers are often used in single-supply voltage circuits and make use of the rail-to-rail output feature these amplifiers have. While the output of these amplifiers can swing close to ...

The EZCT-S2 from Vanguard Instruments is a second-generation, microprocessor-based, current transformer set. The EZCT-S2 will perform the current transformer saturation test and the CT (current ...
