碩士 === 明新科技大學 === 系統晶片與嵌入式系統產業研發研究所 === 98 === HID is belongs to the constant power of gas electric discharge lamp。In tradition，we always use voltage source to contact the current control circuit and provide the stationary constant power to the tube，then，get the change signal of analog voltage and analog current to load into the analog constant power control circuit，and we can get a control of stationary constant power。In view of this essay is use the analog power control circuit，it is complicate and cannot use the control of dimmable，still try to use the digitalize sampling to control the constant power of lamp，make that output power can be stationary。The HID ballast emphasis is the change of constant power from start transient to steady-state，therefore，if we can control these things by digitalize，HID must gain to optimization operation and the tube can work more longer。 In these report，the principle and the design of system hardware control is the one of the instruction emphasis，the others instruction about operation and control measures of circuit system are in the software system flow chart。
