Abstract
A driver may be used to drive an electrically controllable optically active material in a privacy structure. In some examples, the driver receives power from a power source at a supply voltage and a supply apparent power level and converts the power received from the power source down to a converted voltage and a converted apparent power level. The converted voltage is less than the supply voltage and the converted apparent power level is less than the supply apparent power level. The driver may deliver power at the converted voltage and the converted apparent power level to a voltage convertor, which increase the converted voltage to an operating voltage. The driver can further condition power received from the voltage convertor having the operating voltage and operating apparent power level to provide a drive signal and provide the drive signal the electrically controllable optically active material of the privacy structure.
