This paper gives an account of an SCR inverter circuit made up of two inverters with constant voltage and sinewave output. As part of each inverter voltage is tapped out from the resonant capacitors, the control of the output voltage is obtained by the phase-shifting between the two inverters. This SCR inverter circuit not only retains the advantages possessed by the series capacitor-commutated inverter, it is readily regulated just as in the case of the improved parallel capacitor-commutated inverter. Besides,...

This paper gives an account of an SCR inverter circuit made up of two inverters with constant voltage and sinewave output. As part of each inverter voltage is tapped out from the resonant capacitors, the control of the output voltage is obtained by the phase-shifting between the two inverters. This SCR inverter circuit not only retains the advantages possessed by the series capacitor-commutated inverter, it is readily regulated just as in the case of the improved parallel capacitor-commutated inverter. Besides, it has neither filter nor power output transformer. When the desired output voltage (R. M. S.) approaches the d. c. supply voltage, this SCR has optimum performance within the frequency range from 400 Hz to 10 kHz.

At present,if an inverteris removed from the colour TV on the train to get a direct cur- rent directly from the rolling-stock,a frequency modulation controlled-converter must be used. A theoretical analgsis in detail on the output transformer of the controlled-converter is made.A formula is put forward,which can be used to find the relationship between the rate of the relative change of the imput voltage and the load resistance and the rate of the relative change of the cycle of the alternative current on the premise of ensuring the stablity of the output voltage of the direct current of the controlled-converter.Therefore,it has further proved theoretically that when the imput voltage or the load resistance increases, an increase of the frequency of the aiternative current of the output transformer is caused, thus keeping the stability of the output voltage of the direct current.

目前列车彩色电视机若取消逆变器而直接取用车辆直流电源,则需采用频率调制式可控变换器。本文对其输出变压器进行了详细的理论分析,在保证可控变换器输出直流电压稳定的前提下,得到输入电压的相对变化率和负载电阻的相对变化率与交流电周期的相对变化率之间的关系式。因而在理论上进一步证明:若输入电压或负载电阻增加时,将使输出变压器的交流电频率增加,从而使直流输出电压稳定。
