Title: Power conversion apparatus
Inventor: KATSURAYAMA NORIYUKI
IPC: H02M7/06
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To make it possible to utilize regenerative power from a motor effectively by a simple circuit by a method wherein an inverter bridge by which DC power smoothed by a capacitor is converted into AC power so as to be supplied to the motor is installed and a power storage circuit is connected to the capacitor via a step-up and step-down circuit. SOLUTION: In an inverter device, an AC power supply 1 is converted into DC power supply by a rectifier 2. Since the power which is converted by the rectifier 2 contains voltage ripples depending on the frequency of the power supply, it is smoothed into a perfect DC voltage by a smoothing capacitor 3. The smoothed DC voltage is converted, by an inverter bridge 4, into an AC power supply having an arbitrary frequency and an arbitrary voltage, and it drives a motor 5. The main circuit power of the inverter bridge 4 is current- controlled by a step-up and step-down chopper circuit 9 so as to be shifted to a power storage circuit 10. The power storage circuit 10 is a circuit in which a current flowing out from the step-up and step-down chopper circuit 9 can be stored as power, and it is generally a capacitor, a battery or the like.

Title: Electric discharge lamp lighting device
Inventor: YAMAMOTO KAZUYUKI
IPC: H05B41/24
Filed: 1993-12-21
Abstract: PURPOSE:To decrease in-rush current so as to enhance reliability by canceling the cutoff of power supply by a power supply cutoff means only after a power- input time zero-point recognition means recognizes that the voltage supplied from a rectifier circuit becomes zero V. CONSTITUTION:A diode bridge 44 rectifies the supplied alternating current into a direct current and outputs it to a zero-cross starting circuit 45. In the circuit 45, a photoreceptor diode 55 is turned on with more than a predetermined amount of current flowing through the light-emitting diode 52 of a photocoupler, and turns on a transistor 60, thereby keeping an SCR 57 open. If no current flows through the diode 52 at a zero-V point on the next voltage waveform, a current flows through the gate terminal of the SCR 57 via a resistance 58 and the SCR 57 is kept on regardless of the condition of the transistor 60, so that the direct current from the bridge 44 is supplied to a smoothing capacitor 46. Since the current rises from zero, in-rush current is decreased.
