Abstract
An embodiment method of controlling a heating glass includes setting a designated temperature of the heating glass depending on temperature and humidity conditions measured through a sensor, calculating an applied power to reach the designated temperature based on an integrated thermal resistance formed in the heating glass, performing a phase shift of AC power of two or more phases to provide the calculated applied power to a load of the heating glass, and calculating a corrected power in consideration of a resolution of the sensor, wherein respective operations are controlled depending on a set control cycle.

A method of controlling a heating glass, the method comprising:
- setting a designated temperature of the heating glass depending on temperature and humidity conditions measured through a sensor;
- calculating an applied power to reach the designated temperature based on an integrated thermal resistance formed in the heating glass;
- performing a phase shift of alternating current (AC) power of two or more phases to provide the calculated applied power to a load of the heating glass;
- and
- calculating a corrected power in consideration of a resolution of the sensor,
- wherein respective operations are controlled depending on a set control cycle.
