摘要: 本論文提出一個使用於汽車上之泛用型功率驅動電路,它可以根據指令提供多樣化的電壓或電流的驅動曲線 (Voltage/Current Driving Profile) 。主要的目的在於以單一電壓 (12V) 提供多樣化汽車電器所需之驅動功率。初步以提供2A 的電流為目標驗證可行性。本論文的特色在於可程式的功率積體電路,根據所接受的指令,產生所需要的驅動信號,來驅動被控制的元件。舉凡車用燈具所需的閃爍頻率或亮暗程度、馬達驅動的電流大小與驅動曲線、或電子組件的直流電壓,均可以由此一電路提供。如此則能大大的簡化所需之零件,並降低零件的成本。本論文所產出的可程式功率驅動積體電路預計可以達到以下之輸出,一、電壓可程式的直流電源以提供電子組件電源,二、頻率、電壓可程式的交流信號以控制燈具的閃爍與亮度,三、功率曲線可程式之馬達驅動電流以驅動馬達。俱備了以上三種功能,多數的汽車電器裝備將可以由此一積體電路驅動。
This thesis proposes an universal power driving circuit for automobile applications. It can produce the desired voltage or current driving profile, according to the command. The main purpose is to provide multiple driving needs from a single DC power source. The tentative goal is to provide 2A of driving current for the feasibility study purposes. The distinguishing feature is the programmability. According to the command, it can produce the driving signal to driver the driven devices. Not only the flickering frequency and brightness of the light but also the motor driving power profile can be controlled by the circuit. As a result, the cost of the device can be reduced significantly. The proposed programmable power driving circuit is able to produce the following outputs. The first one is the voltage programmable DC power source for electronic equipment, The second one is frequency and voltage programmable for light control. The third one is the power driving profile programmable motor driver. With the above three functions, the majority of the electrical parts in an automobile can be driven by this circuitry.
