Title: Controller for ac/dc converter
Inventor: ARAI JUNICHI
IPC: H02J1/00
Filed: 1987-05-30
Abstract: PURPOSE:To provide a measure against the situation where AC output voltage or reactive power output can not be increased only through control at the side of power inverter, by increasing DC voltage at the side of power rectifier. CONSTITUTION:Power fed from an AC system 1 is rectified through a transformer 2 and an external commutated rectifier 3, then inverted through a self- commutated power inverter 13 and fed through a transformer 14 to an AC system 15. Voltage and current of the AC system 15 are detected respectively through transformers 19, 20, then active and reactive powers are operated and compared with set values. Thereafter, control angle theta and phase psi are varied by an operating unit 40 through a reactive power operating unit 21 and a constant power controller 38 so as to control the power inverter 13. When the capacity of the power inverter reaches to its limit, the phase psi reaches a lower limit which is lower than a referential value psim, and thereby a limiter 52 produces an output which is added to DC voltage setting value Eref of the rectifier 3. Consequently, DC voltage of the rectifier 3 increases.

Filed: 1988-06-02
Abstract: PURPOSE:To reduce unnecessary radiation noise and to suppress unnecessary heating of a resistor by providing at least two circuits for varying the constant of a surge killer circuit and the speed of a diode. CONSTITUTION:When a transistor 8 is turned OFF, no current flows through the input winding 9 of a transformer 7 nor the current is fed back from the base drive winding 10 of the transformer 7, but voltage is produced across the input winding 9 of the transformer 7 in the direction for feeding current, thus boosting the collector voltage of the transistor 8. When a low speed diode 5 is employed, current flows through the electrostatic capacity of the diode 5 to slow the rising of the collector voltage of the transistor 8. During this interval, a diode 6 feeds current through a capacitor 3 and suppresses increase of the collector voltage of the transistor 8. Resistors 2, 4 are employed for the purpose of discharge, and high effect is realized when the capacity of the capacitors 1, 3 is varied.
