HV Modules for piezoelectric actuators

Four quadrant fast and very low noise HV module ranging from -700V to +700V, tested with capacitive loads up to 25nF. Utilized to supply the Fabry–Pérot interferometer of the new optical design conceived for the Interferometric BIdimensional Spectrometer 2.0 (IBIS2.0) that is a focal plane instrument under development to acquire high cadence spectroscopic and spectropolarimetric images of the solar photosphere and chromosphere.

Currently, these power supplies are used primarily in large ground-based telescopes. However, it is important to note that the project was conceived with a specific focus on potential applications in space. The components of these power supplies are selected from those that are radiation-resistant, and qualification tests, including thermal, vibrational, and radiation resistance tests at module level, will be conducted shortly.
IBIS 2.0 will be installed at the Osservatorio del Roque de Los Muchachos in the Canary Islands.
