The invention discloses a driving power supply for intelligent dimming glass. The driving power supply is connected to a power supply with an input voltage of 100-240V. The driving power supply includes an EMI filter, a bridge rectifier circuit, and a high-frequency transformer electrically connected in sequence. The output terminals of the high-frequency transformer are respectively DC80V regulated output circuit and DC12V regulated output circuit; the control terminal of the high-frequency transformer is electrically connected with a PWM control chip; The output end of the variable AC circuit is electrically connected to the power supply glass; the output end of the DC12V regulated output circuit is connected to a 5V step-down circuit, the output end of the 5V step-down circuit is electrically connected to the power supply MCU, and the output ends of the power supply MCU are respectively electrically connected to 200HZ Inverter AC circuit, wireless receiver. The driving power of the present invention has a more stable dimming effect on the adjustable glass, and through the two output voltage stabilization output circuits in the circuit, the dimming glass can achieve a wider range of adjustment, so that the lighting of the glass is more in line with the current environmental requirements.
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...
