IPC: H02J1/00
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a power supply device which is applied to an apparatus the maximum output of which is varied in accordance with a power supply voltage and enhance the power saving effect of the apparatus during small output. SOLUTION: In a large output operation, if a power supply transformer tap changing switch 2 is switched to a contact 2a side, the high AC voltage of the secondary side of a power supply transformer 1 is rectified by a rectifying circuit 3, and a high voltage is supplied to an output amplifier 4. At the same time, a voltage regulation changeover switch 7 interlocked with the switch 2 is connected to a contact 7a side, and a power supply circuit voltage regulation resistor 5 is released and a voltage drops through the series circuit of resistors 5 and 6. The voltage is stabilized by a constant voltage circuit 8 and supplied to a tuner unit 9. In a small output operation, if the switch 2 is connected to a contactor 2b side, the output of the rectifying circuit 3 which is supplied to the output amplifier 4 is reduced.  At the same time, a switch 7 is switched to a contact 7b side and the resistor 5 is short-circuited by the switch 7, and the voltage is supplied to the constant voltage circuit 8 through only the resistor 6. The voltage is stabilized by the constant voltage circuit 8 and supplied to the tuner unit 9.

Title: Ac-excited generator motor driver
Inventor: SHIOZAKI JUNICHI
IPC: H02P9/04
Filed: 1987-04-03
Abstract: PURPOSE:To accurately detect that a semiconductor power converter output stagnates in an inhibiting zone by generating a trigger signal when positive/ negative signs of a slip phase signal is inverted, and discriminating the time interval of the signal. CONSTITUTION:A secondary excitation controller 5 controls a cycloconverter 3 connected to the secondary side of an AC excited-synchronous machine 2 on the basis of slip phase signals 51a-51c from a secondary phase detector 6. Sign inversion detectors 10, on the other hand, output trigger signals 52a-52c in a pulselike state each time the positive/negative signs of the signals 51a-51c are inverted. A comparator 113 operates a slip excessive small relay 116 when the time interval of trigger signals 53a-53c is larger than a time set signal 61. Thus, the stagnation of a semiconductor power converter output in an inhibiting zone can be accurately detected.
