Actuation tests

By martin.lukac@iaac.net | Published: June 12, 2013

Testing the actuation with high voltage electricity and material properties of the membranes at the same time. Membranes appear to be very sensitive to voltage above 4kV. They tend to damage quite easily. Actuation usually starts around 1.3 / 1.5 kV. Discharging capacitor and converter is done manually, via bleeder resistors board. Capacitor should store [...]
