摘要： PROBLEM TO BE SOLVED: To provide an X ray high-voltage generator comprising a converter, an inverter, a high-voltage transformer, and a rectifier, and securing a stable power factor of the converter even if input AC-power-supply voltage changes.
SOLUTION: In the converter 3, two of a half bridge converter 30 and an asymmetric half-controlled bridge converter 31 are connected in parallel. Although the half bridge converter 30 has a good power factor and is stable, the power factor decreases when the input AC-power-supply voltage becomes large. A mixed bridge converter 31 has a harmonic content near a zero crossing point, accordingly, its power factor is slightly lower than that of the half bridge converter 30, however, the power factor does not decrease even when the input AC-power-supply voltage becomes large. So, it is changed to the half bridge converter 30 by an AC input below a reference value voltage. It shall be changed to the mixed bridge converter 31 by the ac input larger than reference value voltage.

摘要翻译：要解决的问题：为了提供一种包括转换器，逆变器，高压变压器和整流器的X射线高压发生器，并且即使输入AC电源，也能确保转换器的稳定功率因数，电源电压变化。解决方案：在转换器3中，半桥转换器30和非对称半控桥转换器31中的两个并联连接。尽管半桥转换器30具有良好的功率因数并且是稳定的，但是当输入的交流电源电压变大时，功率因数减小。混合桥式变换器31具有接近零交叉点的谐波含量，因此其功率因数略低于半桥转换器30的功率因数，然而即使输入的交流电源电压变大因此，通过低于参考值电压的AC输入将其改变为半桥转换器30。通过大于参考值电压的交流输入将其改变为混合桥式变换器31。版权所有（C）2005，JPO＆NCIPI

摘要： PURPOSE:To eliminate the distortion of the tube voltage wave form caused by a response delay of a voltage stabilizing device, by operating first only a DC voltage source, then the DC voltage source and a chopper, and finally the DC voltage source, the chopper, and an inverter in this order, when an X-ray is radiated. CONSTITUTION:By a radiation preperation signal A at first, the rotation of an anode of an X-ray tube 6, and the heating of a cathode heater are started. The signal A also stars the operation if a DC voltage source 1, and voltages V1 and V2 are made to be at a set voltage VD0. Then an X-ray radiation signal B is input to a chopper driving circuit 13, and starts the operation of a chopper circuit 2. After that, at no load operation, when the chopper output voltage V2f before reaching to the normal condition, and a reactor current I2 is at the starting condition, the operation of an inverter 3 is started. In such a condition, since the I2 does not start from zero, the influence of the response delay of the chopper circuit is little. Therefore, the distortion of the tube voltage wave form can be reduced remarka bly.

摘要： PURPOSE:To decrease the fluctuation of the tube voltage wave form of an inverter type X-ray plant and to increase the quantity of X-ray outputs by gradually increasing the on-term of chopping operation. CONSTITUTION:The output signal (e) of an oscillator 35 generates a ramp voltage (f). A function generating circuit 51 generates a pattern signal (l) gradually increasing with the timing of the output signal k of a multivibrator 45 setting the conducting width of the switching element of an inverter circuit. The pattern signal (l) and the ramp voltage f are inputted to a comparator 52, generating the on-off time ratio pattern signal (m) of chopping operation in which the pulse width is gradually increased by means of the frequency of the ramp voltage (f). The output of the comparator 52 is inputted to an AND circuits 48 and 49, outputting the drive signals (o) and (p) of the inverter circuit. A tube voltage wave form having limited pulsation can be obtained by means of the drive signals (o) and (p). If the frequency of the ramp voltage is made to be fully higher than that of the inverter operation, the fluctuation of the tube voltage wave form can be reduced.
