| Abstract: | In this paper, working principle of the power supply with high frequency and high-voltage for X-ray diffractometer is introduced, and a design method is proposed.This new power supply system employs the technology of high frequency(HF), which overcomes many shortcomings such as heavy 、bulkiness and inefficiency in traditional working frequency power supply.Furthermore, pulse width modulation technology(PWM) are introduced to stabilize the signals, which can control and protect the system very well.With the technology of Power Factor Correction(PFC), Power Factor(PF) of this system is improved to 0.9. |
| Keywords: | X-ray diffractometer Pulse Width Modulation(PWM) Power Factor Correction(PFC) working frequency high-frequency power supply |
