The control system of grading light in airdrome that consists of constant-current modulator for light, setting-up transformer, isolating transformer and angle controller of grading light is introduced. 介绍了由恒流调光器、升压变压器、隔离变压器、坡度灯角度控制器等构成的机场坡度灯控制系统。
The open-loop constant-current theory is analyzed and the design basis for the switching frequency, resonant inductor and capacitor, transformer turns ratio is given. 文中对开环恒流原理进行了详细分析,得出开环恒流条件。同时给出了开环恒流驱动器中开关频率、谐振电感电容以及变压器变比的设计依据。
