摘要： PURPOSE:To switch a load current to forward and reverse directions in a high speed with a high precision, by using a circulating current delay circuit to perform the circulating current control at the time when the load current is stabilized. CONSTITUTION:Thyristor converters 12 and 16 of three-phase bridge connection are connected in anti-parallel to a load 18, and both converters 12 and 16 are controlled through pulse phase shifters 26 and 28 in accordance with both currents, which are detected by a circulating current detector 20 and a load current detector 22, and their current commands 104 and 106 by an electronic control circuit 24. The circulating current delay circuit, which attains the deviation between a detected load current 102 and the load current command 104 by a subtractor and compares this deviation with a reference deviation to turn on and off contacts of the circulating current command 106 and a circulating current 100, is added to the control circuit 24. This delay circuit turns off contacts if the deviation is larger when the load current rises rapidly; and if the deviation is smaller, the delay circuit turns on contacts to start the circulating current control.

摘要： PURPOSE:To control a load current at a high speed and with high precision, by employing an actual circulating current as a circulating current command added to a load current command. CONSTITUTION:The load current command 104(A) is inverted by a signal inversion part 31 into a pattern (B) and the circulating current command 106(C) is applied to the 1st and the 2nd thyristor converters, respectively. Then when they flow a current (D) to a load and further flow the circulating current (E), detected currents 100 and 102 are obtained from a current detector. Those detected currents 100 and 102 are applied to an adder 32 by switching the current (E) by a switching part 40 at times T1-T2. This current (E) flows on the basis of the circulating current command 106(C) and includes the delay of the system, etc., so the current command is added to the load current command 104(A) to obtain a command signal (D) of a forward side. Consequently, current control conforming to the load current command 104 and circulating current command 106 is performed at the high speed and with the high precision.

摘要： PURPOSE:To eliminate easily a ripple with software without a filter of hardware, by adding an average value output operating part to the shortest time response controlling part of a lower-level computer. CONSTITUTION:An average value number indicating the number of operation outputs to be averaged and outputted is set to an average value output operating part 12. The target value from an upper-level computer and the feedback quantity from a current detector 6 are taken into the shortest time response controlling part of the lower-level computer. The shortest time control operation is performed on a basis of taken-in data so that an optimum current is flowed to a magnetic field coil. If a plasma current exciting signal of a control interruption signal does not exist, the number of outputs which is set to the operating part 12 are averaged, and the operation result is stored in an operation result table and is outputted. If the plasma current exciting signal exists, the current operation result is outputted without executing the average value output operation.

摘要： PURPOSE:To reduce the load of a control computer, by making sampling in synchronizing with the power supply at the system start and taking the sampling time longer. CONSTITUTION:When a switch SW1 is closed to start the system, the timer t1' is started and the frequency of the power supply 8 is detected from the power supply sychronizing detector 13 to form the sampling period Ts1 at the clock generating circuit and the period is given to the computer 2. The computer 2 detects a current flowing to a load 10 at the period Ts1 to correct the deviation with the control command from the command set circuit 3. This control command controls the trigger angle of a thrysitor converter 9. When the leading of the system is finished, the timer t1' is opened, the switch SW2 is closed, and the pulse in the period Ts2 from the pulse generator 15 is given to the computer 2 as the sampling period.
