TransientBVD - Transient Response Analysis

TransientBVD is a Python library for analyzing and optimizing the transient response of ultrasound transducers (or other resonant systems) modeled by the Butterworth-Van Dyke (BVD) equivalent circuit. It implements advanced methods for both deactivation (resistive damping) and activation (voltage overboost) strategies, significantly reducing transient response times.

This library is developed at the Measurement and Sensor Technology Group, TU Darmstadt to support our ongoing research in rapid transient control for ultrasound transducers. You can find the source code on our lab’s GitHub: TUDA-MUST.
