Versatile waveform generators are required for multiple load characterization and excitation in a wide variety of industrial and biomedical applications. In the past, these generators have been typically limited in voltage/current/frequency due mainly to limitations of the power devices. However, advances in semiconductor and control technologies have enabled the design of high-performance versatile waveform generators with improved operational ranges. This paper deals with the design, optimization and experimental validation versatile 250 Arms, 1 kVpp waveform generator with a 250 kHz bandwidth. Unlike previous proposals, the proposed architecture enables high current operation with a high bandwidth and versatile waveform generation, enabling new testing applications.
