摘要： PURPOSE:To prevent excess cross current from being transiently generated, by making responding speeds in the increasing direction and the reducing direc tion of the output voltage of two sets of thyristor converters(groups), coincide with each other. CONSTITUTION:A three-phase-bridge-connected thyristor is connected to a load 2 in inverse parallel with each other via the cross current suppressing reactor 3a-3b of two sets of thyristor converters 1a-1b, and constant cross current Ic is permitted to flow and is fed from the respective ones. As a current control ling system, a comparator CO, a current controlling section 4, an adder AD and a subtracter DE, and an ignition pulse controller PHC are arranged. In this case, rate-of-change limiting sections 6a-6b for limiting a change degree on every sample of input signals ECa-ECb of said controller PHC are arranged, and the characteristic of the variable gain is turned into characteristic changing a gain in both the positive and negative directions of a control error. As a result, the variable gain is varied, and speeds in the increasing and reducing directions of the output voltage Va, Vb of the thyristor converters 1a-1b can be made equal to each other, and the control in good order can be performed.

摘要： PURPOSE:To rapidly and stably recover the speed drop of a motor generator at the load time of the generator by calculating the optimum initial pole position and the high speed electrode driving time for accelerating from the present motor speed to the target speed in the minimum time. CONSTITUTION:An initial electrode position controller ISR reads out a detecting speed omega and an electrode position signal P of the secondary liquid resistor 8 of an induction motor for driving a motor generator 3 when the difference DELTAomega between a target speed omegaref and the detecting speed omega is the prescribed positive value alpha or higher, calculates the optimum electrode position Pref for accelerating the generator 3 at the rated current of a motor, and calculates the high speed electrode drive time (t) to the optimum electrode position. The high speed electrode drive circuit 7 is operated during the time (t). Thereafter, the electrode position of a liquid resistor 8 can be controlled by a speed controller ASR and the current controller ISR.

摘要： PURPOSE:To control a plasma current by providing a selection part which inputs the output signal of a current limitation control part and a signal corresponding to the terminal voltage across an ohm heating coil and selects and outputs one of them. CONSTITUTION:A current detector 30 detects the current IOH of the ohm heating coil 3, the current limitation control part 31 amplifies the sum of said current and the value corresponding to a permissible current IN, and its output signal x2 is compared with the output signal x1 of a plasma control part 22. The result is inputted to the selection part 32 which selects and outputs the smaller current, and the output voltage V2 of a 2nd thyristor converting device 21 is adjusted according to the output signal x3 of the selection part 32.

摘要： PURPOSE:To simplify transfer function of a controller and easily perform control by controlling the applied voltage of an ohmic heating coil on the basis of a plasma current signal. CONSTITUTION:A plasma current signal SIP output from a signal output circuit 108 of a plasma current detecting system 107 is input in an adder-subtracter 110 of a plasma current controller 109, at the same time a plasma current desired value signal Ipref is input and a deviation signal epsilon is output. The deviation signal epsilon is input in a controller 111, a corresponding voltage control signal SVOH is transmitted to an electric power unit 105 and the voltage VOH applied in an ohmic heating coil 103 is proportionally controlled. Therefore, since the form of the controller is simple, control is easily performed in the case where digital control is performed by a computer.
