Introduction of High Precision Charging Technique Applied in Pulsed Magnetron Modulator for Industrial Computerized Tomography System
In this paper the charging technique used in PMM (Pulsed Magnetron Modulator) of ICT (Industrial Computerized Tomography) system is introduced. This charging technique is based on the high frequency series resonant inverter technology,which is applied in many kinds of power supplies or modulators. For high spatial resolution and high density resolution in ICT,the required precision of output voltage between pulses of PMM is more than 99.9%. Based on the requirement of output parameters of PMM (shown in Table 1), a two-stage series resonant charging technique is adopted. First stage is fast-charging stage which lasts 2ms, and the PFN (Pulse Forming Line) could be charged to 97% of rating voltage in the end of the stage.Second stage is slow-charging stage which lasts 0.6ms and ensures the voltage of PFN varies less than 0.1% between pulses.
