What is electronic loading?
An electronic load is a test instrument designed to sink current and absorb power out of a power source. Device manufacturers and design engineers use electronic loads to test power devices such as power supplies, DC-DC converters, chargers, adapters, batteries, solar panels, fuel-cells, and more.
What is programmable DC electronic load?
A programmable load is a type of test equipment or instrument which emulates DC or AC resistance loads normally required to perform functional tests of batteries, power supplies or solar cells.
What is a DC electronic loads?
An electronic load is a type of instrument that applies a voltage and sinks current. Also known as a DC programmable load, these AC or DC electronic loads are used by power supply, battery, solar, wind, or other manufacturers who want to thoroughly test their power sources.
What should be considered when designing an electronic load circuit?
Careful selection of the circuit components is critical to the performance and durability of the final electronic load circuit. The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered:
What to add to an electronic DC load?
In Part 4 of this project on the Electronic DC Load we are going to add a remote voltage sense circuit, increase the power capacity by adding additional power mosfets and build the completed unit into a metal project case. We will also upgrade the software to allow for input entry via the keypad as well as the rotary encoder.
