摘要： PURPOSE:To improve the economy by setting the minimum control angle of a thyrister converter in a variable manner depending on the intensity of a load current when an AC voltage generated by an AC generator is rectified by means of a thyrister converter and then is supplied to a load. CONSTITUTION:An output from an AC generator 1 is rectified by means of a thyrister converter 11 and a DC power is supplied to a load. Also a generator current is detected by means of a current transformer 15 and a detection circuit 16 and then is input to a minimum control angle decision circuit 19 on a thyrister converter 11. In addition, a thyrister converter output current is detected by a current transformer 17 and a detection circuit 18 and then is input to a control angle decision circuit 20. Following this process, the both outputs from the said circuits are compared by a comparator 21 and a larger one is supplied to an ignition signal generation circuit 22. Consequently, it is possible to minimize a minimum control angle to the smallest degree as required against a bias in an AC power supply wave form because the minimum control angle is set in a variable manner according to the intensity of a load current, thus enhancing the economy.

摘要： PURPOSE:To prevent overload due to the variety of loads, by calculating average output power corresponding to conduction time for every period of power supply for comparison thereof with allowable average power to decrease the output voltage of a generator. CONSTITUTION:The voltage, current and power of an AC generator 1 supplying pulse power to the load 16, nuclear fusion equipment, etc. are detected by detectors 11, 12, 13 to input into the monitor controlling device 17 for the control of the field winding 6 of the generator 1 via a voltage controller 10 and thyristor rectifier 7 by the output thereof. Besides, the monitor controlling device 17 is constituted of a process input-output unit 171, arithmetic control unit 172 and in put-output 173 to calculate average output power for every period of power supply with the generation of output by comparing with allowable average power. Therefore, the varieties of loads and operating patterns produce no over load in the generator 1 to effectively apply the capacity thereof.

摘要： PURPOSE:To provide a thyrister converter of small capacity by first starting a thyrister converter and then switching on a diode converter when the diode converter and the thyrister converter are connected in series to supply an electric current to a load. CONSTITUTION:Diode converter 31, 32 and a thyrister converter 33 are connected through the intermediary of an AC breaker 11-13 and a transformer for conversion 21-23 and the DC sides of the converters are mutually connected in series to supply an electric power to an induction load 40. Then as an operating sequence, first the breaker 13 is switched on to start the thyrister converter 33 and the load 40 is applied with a high voltage to excite rapidly upto a prearranged current value by switching on the breakers 11, 12 in a state where a small amount of current is run. Consequently, it is possible to use the thyrister converter 33 of extremely small capacity because the diode converters 31, 32 are started under a state where a small amount of current is run and therefore, improve the economy.

摘要： PURPOSE:To enable switching of polarity of a DC power supply at high speed by providing a breaker and thyristor at both ends of the power supply for switching the polarity of the power supply and triggering the thyristor by the restarting voltage of the breaker at breaking time. CONSTITUTION:A DC power supply RF is connected through vacuum breakers VS1, VS2 and main breaker CB for switching the polarity of the power supply to a load L for imparting an energy to a plasma at a nuclear fission reactor. The main breaker CB is opened at a point a of the load current to flow reverse current from a capacitor C. Then, the breakers VS1, VS2 are opened when the current reaches the time t2 to trigger the thyristors SCR1, SCR2 via potential dividers PD1, PD2 by restarting voltage to thereby switch the polarity of the power supply to the load L. Thus, it can switch the polarity at high speed to maintain the plasma current costant.

摘要： PURPOSE:To perform AC discharge washing operation through compact facilities, by providing a signal-phase transformer having a middle tap and by selectively using thyristor switches for a high-temperature plasma generator through a simple switch circuit. CONSTITUTION:Connecting switches 34-36 to sides (b), a voltage is applied from a power supply transformer 300 to thyristors 22, 28. When a forward voltage is applied to the thyristor switch 22 or 28, a turn-on pulse is supplied thereto so that plasma is produced by a current transformer coil 17 and the washing is performed. Then, the other thyristor switch is turned on. Namely, the thyristors 22, 28 are alternately turned on. Thereby, the washing can be continued.

摘要： PURPOSE:To eliminate the production of an abnormal voltage in a coil at the abnormally erasing time of a plasma current by detecting a voltage between the anode and the cathode of a thyristor and firing a thyristor when the voltage becomes larger than the prescribed value. CONSTITUTION:When a plasma current is abruptly decreased or erased, the current of a current transformer coil 4 decreases in the negative absolute value, and the current is intermittently flowed. Since the overvoltage which is produced in the coil 4 at this time becomes forward to the thyristor 14, this voltage is detected in a self-firing type gate circuit 15, and when it exceeds the prescribed overvoltage level, it generates a gate signal to fire the thyristor 14. Then, the coil 4 is shortcircuited, thereby preventing a high voltage from being generated between the terminals.
