    摘要: A power converter apparatus has at least two converters CONV1 and CONV2. The DC side of each of the converters CONV1 and CONV2 is connected to a filtering capacitor Cd which serves as a DC power source for a load device LOAD. The AC side of the converter CONV1 is connected to the secondary winding of a first transformer TR1. The AC side of the converter CONV2 is connected to the secondary winding of a second transformer TR2. The primary winding of transformer TR1 is connected in series to the primary winding of transformer TR2. The series circuit of the primary windings of transformers TR1 and TR2 is coupled to an AC power supply SUP via a single AC reactor Ls. A control method of the invention is adapted to the power converter apparatus in which plural PWM converters are used. The phase of a modulating wave (carrier) of one PWM converter differs by a predetermined degree from that of another PWM converter.

    摘要: An automatic running work vehicle in which both front wheels and rear wheels can be steered and which is provided with a follower sensor for detecting the boundary between an unworked area and a worked area and an orientation sensor for detecting the running direction so as to run automatically along the boundary. Based on the result of detection of the boundary by the follower sensor and on the result of detection of the orientation of the vehicle body by the orientation sensor, the front and rear wheels are steered automatically to correct the running direction automatically.

    摘要: An AC current detection circuit is intended to detect whether an AC induction current for the rotor of the rotating anode X-ray tube flows or not. A current transformer is employed in the rotor supply circuit to generate a lower voltage at its output circuit by utilizing its magnetic-electric conversion effect. A transistor will switch on-off by receiving the generated voltage and produce a series of output pulse signals. A retriggerable monostable multivibrator will detect a missing pulse from the output pulse signals, which indicates a failure of the rotor supply operation.

    摘要: A circulating current of a cycloconverter in each phase is distributed and controlled in such a way that a circulating current in a phase having a large absolute value of a load current is small, and the circulating current of a phase having a small absolute value of the load current is large. Therefore, the reactive power is so compensated that the sum of lagged reactive powers of the phases and advanced reactive power of a phase advancing capacitor cancel out each other.
