A bi-directional current source for a grounded load will always have some complication in its construction. The improved Howland Current Pump as shown in Figure 1 is the most frequent choice for this ...

A current transformer (CT) is a simple, practical and inexpensive means of detecting the presence of AC current. Detecting load current rather than applied voltage is a superior method of determining ...

Part 1 of this series focuses on high-performance electronic loads for testing power supplies that have low output voltage and high current. It describes the necessity for special electronic loads, ...

How to replace MOSFETs with load switches, and the impact of on-resistance. Swapping out diodes with ideal diodes, and the use of ideal-diode controllers. Why replacing fuses and resettable fuses with ...
