The new KD *P controller permits a very short switching time as well as a stable of electric power supply, making it possible to obtain multiple frames in a single phase of high voltage. Here we have used a 80C196KC microprocessor and three high voltage modules. The rising and falling time of output pulses generated from the new controller is found to be less than 10 -3 sec and the power supply stability is maintained within accuracy of less than 0 1%. The period of a single phase voltage is controlled by user in the range of 0 03sec to 3 seconds. The number of integrated image frames is also set by user up to 256 frames. The present system can be readily utilized to control a wider range of high voltage power by simply modifying software.展开更多
