Title:
THREE-PHASE AC/DC CONVERSION DEVICE, PHOTOCHEMICAL REACTION DEVICE AND METHOD USING SAME, AND METHOD FOR PRODUCING LACTAM
Document Type and Number:
WIPO Patent Application WO/2016/059942
Kind Code:
A1
Abstract:
Provided is a three-phase AC/DC conversion device disposed between a three-phase AC power supply and a light-emitting diode group, the device comprising: a three-phase full-bridge circuit in which pairs of switching elements are connected in parallel between three-phase DC buses for the three-phases of the three-phase AC power supply; reactors connecting connection portions between the switching elements and corresponding phases of the three-phase AC power supply; a smoothing capacitor on the output side of the three-phase full-bridge circuit; a DC voltage detection means; a power supply voltage phase detection means; and a pulse width modulation means for outputting pulse width modulation signals of the switching elements, wherein the pulse width modulation means outputs the pulse width modulation signals on the basis of a power supply voltage phase and an output voltage between the DC buses. The present invention further provides a photochemical reaction device and a photochemical reaction method that use the device and a method for producing a lactam using the photochemical reaction method. The present invention makes it possible to cause the light-emitting diode group having a large capacity to stably and continuously illuminate while suppressing an occurrence of a voltage reduction phenomenon and suppressing an influence on the AC power supply, thereby contributing to the stabilization of the photochemical reaction.
