| description | Polymer Dispersed Liquid Crystal (PDLC) glass, with its controllable light transmittance enabling shading and energy savings, is widely used in green and smart buildings as a key technology for smart windows and privacy glass. However, traditional PDLC drivers are bulky, consume high energy, and offer limited functionality, restricting their application in multi-panel glass control and space-constrained scenarios. This study proposes a low-power, adjustable mini driver that utilizes Pulse Width Modulation (PWM) signals and a full-bridge inverter architecture to generate AC square waves. By integrating simple analog and digital circuit designs, digital resistors, and specialized adjustable power modules, remote voltage and frequency modulation control is achieved, enabling efficient and flexible PDLC driver development. Compared to traditional transformer designs, the developed driver not only offers the advantages of miniaturization and high efficiency but also can flexibly adapt to diverse application scenarios such as office privacy glass, smart buildings, and multi-zone linkage control. This research provides an effective solution for the widespread application of PDLC technology and the advancement of smart buildings. Finally, the functionality of the proposed design is verified through hardware circuit implementation and experimental validation. |
