The electrical characteristics of the PT are investigated to obtain a higher voltage gain by adapting the load impedance to the interposed network. The circuit parameters are selected under the considerations of (1) the minimum inductor size, (2) the higher circuit efficiency, (3) the rated current of the PT, and (4) the stable lamp operation. The electronic ballasts are designed for operating the lamp at the rated lamp power and with dimming control by asymmetrical pulse-width-modulation (APWM),respectively. Laboratory circuits are assembled and, experimental tests are carried out to validate the theoretical analyse Chin-Sien Moo 莫清賢 2002 學位論文 ; thesis 74 zh-TW
