Low power driver for privacy glazing

An electrically dynamic system comprising:

• a first pane of transparent material;
• a second pane of transparent material;
• an electrically controllable optically active material positioned between the first pane of transparent material and the second pane of transparent material, the electrically controllable optically active material being positioned between a first electrode layer and a second electrode layer;
• and
• a driver electrically connected to the first electrode layer and the second electrode layer,
• wherein the driver is configured to:
• electrically connect to a power source that provides power at a supply voltage and a supply apparent power level;
• convert power received from the power source down to a converted voltage and a converted apparent power level, the converted voltage being less than the supply voltage and the converted apparent power level being less than the supply apparent power level;
• deliver power at the converted voltage and the converted apparent power level to a voltage convertor;
• at the voltage convertor, increase the converted voltage to an operating voltage, thereby providing power from the voltage convertor at the operating voltage and having an operating apparent power level;
• 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 to the first electrode layer and the second electrode layer for controlling the electrically controllable optically active material, and
• wherein the driver comprises:
• a first housing containing a power convertor configured to convert power received from the power source down to the converted voltage and the converted apparent power level;
• a second housing physically separate from the first housing, the second housing containing the voltage convertor and circuitry configured to condition power received from the voltage convertor;
• a first wiring extending from the power source to the first housing;
• a second wiring extending from the first housing to the second housing;
• and
• a third wiring extending between the second housing and the first and second electrode layers, the drive signal transmitting along the third wiring to the first and second electrode layers,
• with the first wiring comprising a thicker conductive member than conductive members in the second wiring and the third wiring.
