Therefore, to complement, we made a device that can generate high-dose radiation by using a high-capacity capacitor. The mobile X-ray device was designed for high factor and reduction in power consumption by applying pulse frequency modulation capable of variable driving frequency in a high voltage-generating device. In this paper, we studied frequency and output characteristics varying depending on the load fluctuation of the mobile X-ray machine. As a result, exposure dose and operation frequency linearly increased or decreased, depending on the changes in tube-voltage and tube-current.
