Electronic loads-a new generation

This article describes some advantages and disadvantages of the DC electronic loads technology alternatives and presents a newly developed, hybrid circuit topology offering some unique performance features. Most electronic loads using resistive elements are fabricated by end-users wanting high-power, low-cost solutions for their testing needs, sacrificing dynamic loading and programmable protection capabilities. Metal oxide field effect transistors (MOSFETs) can be deployed as the latest electronic loads to address the limitations of resistor-based loads. These electronic loads use semiconductor devices, operated in the linear region, to allow full power and full control over the entire VA rating of the product.
