| Abstract(in English) | Conventional DC power supplies are normally designed for constant power applications and do not perform well under the wide range of load. A power supply specially designed for x ray power generator applications that use a 32kHz series resonant circuit topology with a multistage voltage multiplier instead of a conventional high voltage diode rectifier connected to the second-side of a high-voltage transformer, a constant ontime/variable frequency control scheme, and zero-current switching technique has been newly developed. According to introducing the multistage voltage multiplier, the secondary turn numbers, layers, and stray capacitance of transformer as well as the rectifier diode voltage ratings can be greatly reduced. It is proved that the proposed converter topology and control sheme is suitable for high-voltage applications on the basis of simulation analysis and observed data in experiment. |
