Testing power supplies and batteries requires current loads capable of sinking large current and dissipating substantial amounts of power. A simple but accurate current load can be built using just a ...

Here’s a handy little current source that’s often used to control the current flowing through a load. Find the equation that defines the i-Load current and account for non-ideal sources. The i-Load ...

Automotive, industrial, and FireWire peripherals all call for high-efficiency, space-saving power supplies with high current capabilities at very high voltages. The problem is that high-voltage, ...

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, ...

Here is a simple method for estimating the actual load on an electric motor without special equipment. But first, a word of caution: Some applications (e.g., a large forced draft fan) require more ...

Constant current limiting circuits are commonplace, but sometimes a constant power limiting function is desired instead. This can be because downstream loads, like DC/DC converters, present a constant ...
