PAGE II 水晶闪电球电源的设计 摘要 水晶闪电球是一种新型的灯饰器具，正受到越来越多人的青睐。其内部的惰性气体在高压电场的激发下会发生电离，从而发出辉光。水晶闪电球的电源是一种高频，高压的脉动直流电源。但是当前所研制的闪电球电源输出电压不稳定，只有部分电源支持声控模式，却只能控制灯的亮灭，而无法根据声音大小实现亮度变化，功能较简单。 本课题深入研究了水晶闪电球的电源系统，使用STM32作为主控芯片，其产生的高频高压脉动直流电为闪电球供电。本系统拥有完整的交互界面，使用TFT液晶触控显示屏作为人机交互媒介，拥有多级菜单界面，可以在多种功能之间进行切换；支持TF卡读取，能显示彩色图片与中文字体；支持触控，可以直接点击屏幕进行操作。在普通模式下，支持触控进行多级亮度调节，在声控模式下，能根据周围环境音量变化改变亮度。本系统功能强大，稳定性好，精度高，能广泛的应用于需要小功率高频高压脉冲直流源的场合。 关键字：高频高压脉动直流电源；数字开关电源；STM32应用；交互界面 Power source design of plasma magic light Abstract Plasma magic light is a new type of lighting apparatus .It is becoming more and more popular. There are inert gas in the light. Under the excitation of high voltage ionizes, It will glow. The power of the Plasma magic light is a kind of high frequency, high voltage pulse dc source. But for now, the power source of plasma magic light is not stable. Only part of the power supply supports voice-activated mode, but can only control the lights on or off, not be achieved according to the sound volume brightness, functions are simple. This project studied the power systems of plasma magic light, use the STM32 as the main control chip, which produces high-frequency high-voltage pulsating direct current to power bolt. The system has a complete interface, use the TFT LCD touch screen, with a multi-level menu interface. Users can switch between the various functions. Support TF card reader, can display color pictures and Chinese font. Supports touch, you can directly click on the screens on the. In normal mode, supports multilevel brightness adjustment. In voice-activated mode, change brightness according to the ambient volume change. This system is powerful, good stability, high accuracy and can be widely applied where low power high frequency and high voltage pulsed DC source is required.
