专利汇可以提供X-ray tube voltage controller专利检索,专利查询,专利分析的服务。并且PURPOSE: To perform accurate X-ray tube voltage, by controlling the phase of trigger pulse through the comparison fo the set tube voltage with the peak value of the tube voltage at transparency when holding.
CONSTITUTION: The voltage form AC power input 17 (waveform A as full wave rectified) is fed to the high voltage transformer primary side as the waveform C (solid lines) with the trigger pulse B fed to the switching circuit 19, and the secondary voltage similar to this is smoothed in the capacitive component of the high voltage cable C after being rectified, and the voltage in proportional to the peak value of the primary (secondary) voltage is fed to the X-ray tube 22. After the primary voltage is rectified, it is inputted to the peak hold circuit consisting of the operational amplifier 4, capacitor 6, output circuit 9 and resistor 10, and the voltage in proportional to the peak value of the primary voltage is held. Further, it is compared with the set value of the tube voltage setter 11 at the phase control circuit 12, and the phase of the trigger pulse B generated is controlled. Further, every generation of trigger pulse, the capacitor 6 is discharged and the output voltage of the circuit 12 is reset every pulse as the waveform D, and the response of the phase control is quickened
