Electronic loads are circuits that consume electrical energy. Several problems exist in the development and evaluation of power supplies, for example, the inability to prepare the original load or the time and effort required to prepare a substitute load by using passive electronic components, such as resistor.
Moreover, behaviors that are difficult to reproduce with a real load, such as load fluctuations (changes in resistance), can be easily reproduced using an electronic load.

  • Electronic load applications: Power supply circuit evaluation
  • Advantages of using electronic loads: Facilitate safe testing under load fluctuation conditions.

Typical electronic loads dissipate power as heat. Regenerative electronic loads and regenerative power supplies (bidirectional power supplies) return the power at the load to the alternating current (AC) power grid.
For high-power electronic loads, regenerative electron loads and regenerative power supplies are advantageous in terms of electricity costs and exhaust heat treatment.
