Abstract

Present invention discloses an intelligent privacy glass drive power supply. The drive power supply is connected to a power supply having an input voltage of 100-240 V. The drive power supply comprises an EMI filter, a bridge rectifier circuit, and a high frequency transformer electrically connected successively. Output terminals of the high frequency transformer are a DC 80 V constant voltage output circuit and a DC 12 V constant voltage output circuit respectively; a PWM control chip is electrically connected to a control terminal of the high frequency transformer; a 200 HZ inverter AC circuit is electrically connected to the DC 80 V constant voltage output circuit, and an output terminal of the 200 HZ inverter AC circuit is electrically connected to power supplied glass; a 5 V step-down circuit is connected to an output terminal of the DC 12 V constant voltage output circuit, and an output terminal of the 5 V step-down circuit is electrically connected to a power supplied MCU; an output terminal of the power supplied MCU is electrically connected to the 200 HZ inverter AC circuit and a wireless receiver respectively. The drive power supply of the present invention has a more stable dimming effect on privacy glass, and enables the privacy glass to reach a greater degree of regulation through two output constant voltage output circuits in the circuit, thus being more suitable for current environmental requirements for glass lighting.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to an intelligent dimming glass driving power supply. Background technique [0002] Glass windows transmit light, block wind and dust, and are an essential component of buildings and homes. In summer, as the outdoor temperature rises and the light increases, the indoor light and temperature will also change. People have to turn on the air conditioner or close the curtains. Friends who drive need to prepare a reflector in the car to prevent direct sunlight. If there is a glass that can adjust the light, this problem will be solved, so the smart dimming glass will come into being. Smart dimming glass can control the transmittance of visible light and ultraviolet light according to changes in indoor and outdoor light or temperature. This kind of smart dimming window will greatly reduce the use of air conditioners and curtains, which greatly facilitates our lives and makes our lives more...
