摘要： PURPOSE:To detect an error pulse mode due to a fault of an intermediate mode of a gate of a PLL circuit by providing a detection circuit detecting whether or not an input voltage of a voltage controlled oscillator is within a prescribed reference width in a phase locked loop (PLL) circuit. CONSTITUTION:The detection circuit 100 consists of an amplifier A1 amplifying a reference voltage Vr.f, an amplifier A2 outputting a voltage with different voltage value from the reference voltage, an amplifier A3 amplifying a prescribed reference voltage DELTAVt, amplifiers A4, A5, comparators A6, A7 comparing an input signal ef and a reference width DELTAVt and an inverse amplifier IV inverting the output. When the detected input signal et is within a prescribed width DELTAVt, an output V'out goes to a low level and goes to a high H level at an error and an error pulse mode is detected. Moreover, since the circuit contributes largely to the troubleshooting at maintenance, the repair time is reduced and also this circuit is effective to improve the system availability.

摘要： PURPOSE:To ensure the stable control even though the input of a control circuit has an error, by obtaining the deviation of each control output value to the desired value and using this deviation to unify each control output value. CONSTITUTION:A reference signal 100 is supplied to a selecting circuit 14 via differential circuits 10A-10C and control circuits 12A-12C. The circuit 14 consists of maxium value selecting circuits 16A-16C and minimum value selecting circuits 18A and 18B and selects one of the control signals supplied from circuits 12A-12C to apply it to a control subject 20 as well as to differential circuits 22A-22C respectively. The circuits 22A-22C calculate the deviation between the control signal applied to the subject 20 and the output signal of each of circuits 21A-12C and apply the deviation to circuits 10A-10C via compensating circuits 24A-24C. The circuits 10A-10C obtain the difference between the signal 100 and a feedback signal 108 given from the subject 20 and then compensates the difference by the signals given from circuits 24A- 24C. This compensated difference is applied to circuits 12A-12C respectively.

摘要： PURPOSE:To reduce the difference at point of time of a pulse output, by inputting the same types and values of inputs used at the software of each digital device and making the operation processing periods among the digital devices coincident with each other as much as possible. CONSTITUTION:A multiplex processing section 11 controls a trigger angle by selecting one pulse. Each operating section 7 obtains a current input from a respective input section 6 and introduces current inputs of other digital devices via a photoelectric converter 13 and an optical cable 12. One signal out of three current inputs introduced is used for the operation at each section 7. The same value is used for each operation section for the operation. A clock 14 specifying the operation period of each digital device is synchronized with an external forced signal 21. It is required for the forced signal 21 to be generated suitably, and in this case, the signal is generated in synchronizing with the zero point of a voltage signal.

摘要： PURPOSE:To enhance the reliability and the accuracy of a DC transmission converter by providing an insensitive band circuit at the input side of a frequency correction controller, thereby preventing the output error from increasing as the time elapses by the irregularity of the detector of the frequency correction controller. CONSTITUTION:insensitive band circuits 15-1-15-3 are provided at the input side of the frequency correction controllers 3-1-3-3 of 1-3 system controllers. These circuits 15-1-15-3 have insensitive band of the degree which absorbs the irregularity of the detectors of the controllers 3-1-3-3. Therefore, the controllers 3-1-3-3 do not operate by the irregularity of the detectors of the controllers 3-1-3-3, and the set power values of the 1-system, 2-system and 3-system controller do not vary.
