Patent JP-H05336755-A (JP)
Title: Power supply equipment
Inventor: HIRAOKA TOSHIYUKI
IPC: H02M7/537
Filed: 1992-06-03
Abstract: PURPOSE:To provide a power supply equipment wherein harmonic components of its input current can be reduced and the reductions of its size and its price and the simplification of its configuration are made possible, together with its capability relative to the reduction of the generative quantity of its noise. CONSTITUTION:The AC voltage fed from a commercial AC power supply E is rectified by a full-wave rectifying circuit 11, and a first capacitor C11 is charged by the output voltage of the circuit 11. Then, an electric power is fed to a high-frequency inverter circuit 16 via a diode D11, and in the high-frequency inverter circuit 16, an oscillation is caused. When the input current wave shape fed from the power supply E is large in comparison with the input voltage wave shape fed therefrom, since such loads as the high-frequency inverter circuit 16 are light, by making the frequency of the oscillation high, impedances are made large, and the loads are made large. When the input current wave shape is small in comparison with the input voltage wave shape, since such loads as the high-frequency inverter circuit 16 are heavy, by making the frequency of the oscillation low, the impedances are made small, and the loads are made small. Further, the input current wave shape is approximated to sine wave, while adapting it to the input voltage wave shape, and its higher-order harmonic waves are reduced.

IPC: H02H7/08
Filed: 1980-10-15
Abstract: PURPOSE:To protect a DC motor by giving taper charateristics to the current limit value of a current limit circuit with a rise of the speed of revolution by voltage generated from the DC motor, which is inversely proportional to speed, and correcting the protective device so as to increase load currents. CONSTITUTION:Speed reference signals 11 and speed feedback signals 12 are compared through resistors 31, and the deviation signals are inputted to an amplifier 13A. The output of the amplifier 13A is used as the current referrence signal of an  amplifier 13B for controlling currents, and compared with current feedback signals 15. That is, the current reference signals are limited by controlling the output signals of the amplifier 13A. In this case, the signals are limited by means of a transistor Tr33 and a diode Di34 lest the current reference signals of vlue or higher set by means of a current limit value setter 35 should be outputted. The current limit value in relatinship, which is inversely proportional to the number of revolution, can be added to the amplifier 13A by adding detecting signals 32, which are inversely proportional to the speed of the DC motor not shown, to the base potentional of the Tr33 through the Di34 as correction signals.
