APPARATUS FOR CONTROLLING HEATING OF HEAT-DISSIPATING GLASS Russian patent published in 2013 - IPC H05B1/02 

FIELD: physics.

SUBSTANCE: invention relates to an apparatus for controlling heating of a heat-dissipating glass, which transmits a sinusoidal signal in accordance with the size of the heat-dissipating glass such that the sinusoidal signal is transmitted at a moment in time when current of the sinusoidal signal is equal to zero, and transmission of the sinusoidal signal stops at a moment in time when current of the sinusoidal signal is equal to zero. The signal is transmitted to the heat-dissipating glass so as to control power supply taking into account the load created by the heat-dissipating glass, and the moment the sinusoidal signal passes through zero is determined using a phase detection portion, and heat control portion generates a control signal so that the signal is transmitted at a moment in time when current of the sinusoidal signal is equal to zero, and also transmission of the sinusoidal signal stops at a moment in time when current of the sinusoidal signal is equal to zero, and then transmits the control signal to a former, and the signal transmitted from the power supply portion is transmitted through the signal former to the heat-dissipating glass, and each signal transmitted to each heat-dissipating glass can be transmitted in different periods of time.

EFFECT: reduced noise generation, high reliability and longevity.
