摘要： A control system for a variable transmittance optical filter assembly includes a controller in communicatively coupled to a pair of load terminals, and a memory communicatively coupled to the controller and having encoded thereon statements and instructions executable by the controller to transition the optical filter assembly between operating states when coupled to the pair of load terminals. The controller is operable to perform any one or more of: allowing the optical filter assembly to transition to a dark state by shorting the load terminals together, maintaining the optical filter assembly in a hold mode by applying a pulse width modulated voltage signal across the load terminals, and transitioning the optical filter assembly between operative states by applying a voltage signal having voltage pulses of opposite polarities to the load terminals.
