技術說明

研發適用於不同大小面積之泛用型冷光板模組化驅動控制器，以提升冷光板使用壽命及縮短冷光板廣告開發時間。 利用可程式單晶片(Programmable System on Chip, PSoC)作為核心控制器，以SHE-PWM(Selective Harmonic Eliminate PWM)來提供全橋換流器開關驅動控制訊號、模組化多段跳觸發訊號及脈波寬度調變(Pulse Width Modulation, PWM)漸亮暗調光控制訊號等。 最後在與市面上販售之冷光板驅動器做比較，證明本驅動器較市售驅動器具有更高的適用性與多樣化。 Research and developmenting a general purpose Electro Luminescent (E.L.) panel for the universal modular drive controller, the E.L. life expectancy could be extended and shorten the development time for E.L. advertise panel. By optimizing the Programmable System on Chip (PSoC) as the core control unit, which providing Sinusoidal Pulse Width Modulation (SPWM) to control the full-bridge inverter switch, multi-hop trigger signal, and Pulse Width Modulation (PWM) signals for the gradually light and dark dimmer control. At last, on the market of E.L. panel driver compare with this universal modular drive controller to prove that this driver has higher flexibility and diversification than the market of driver.
