Load Emulation

Active Load Emulators are very relevant in inverter test bench technology. An inverter is an electronic device that converts direct current (DC) to alternating current (AC) or changes the frequency, voltage or phase angle of the AC output. Such inverters are used in various applications, including renewable energy sources such as wind or solar energy, electric vehicles, industrial installations and more.

Load simulation: Inverters must be tested under various load conditions to ensure they can deliver expected performance and stability. Active Load Emulators enable simulation and testing of the output power produced by the inverter in a controlled environment.

Power hardware in the loop: Due to the regenerative feedback made possible by the use of this technology, energy requirements are significantly reduced.

Efficiency testing: The efficiency of an inverter can be measured by simulating different load conditions. An Active Load Emulator can load the inverter with variable loads and evaluate its efficiency over the entire operating range.

Dynamic testing: Inverters often need to handle rapid load changes, especially in applications such as electric vehicles. An Active Load Emulator can replicate such dynamic load changes and evaluate the inverter's ability to respond quickly.

Stability checks: Inverters must operate stably, without causing unwanted oscillations or instabilities in the system. Simulating different load conditions with Active Load Emulators can help verify inverter stability.

Development and validation: When developing new inverters or updating existing models, Active Load Emulators facilitate thorough validation and optimization before the inverters are deployed in real-world applications.

Overall, Active Load Emulators are indispensable tools in inverter test bench technology to analyze and ensure the performance, reliability and interaction of inverters with the grid or other energy sources.
