Title:
INTERMITTENT OPERATION LOAD POWER SUPPLY SYSTEM
Document Type and Number:
Japanese Patent JP2008072860
Kind Code:
A
Abstract:

To reduce the voltage drop width of a load and the voltage drop width of a commercial power source side to the tolerance range, and to control faults due to flicker phenomenon that occurs in the other load.

In a power supply system, power is supplied to a load 21 which repeatedly performs intermittent operation by an operation time T and in which a permission voltage drop width is set to be VL from a commercial power source 1, in which an allowed voltage drop width of rectifier output is set to be VS via a rectifier 23 and a voltage-smoothing capacitor 25. A voltage compensation capacitor 26 with a capacitance C is connected in between an output circuit of the rectifier 23 and the voltage smoothing capacitor 25, in parallel. The voltage compensation capacitor 26 and the voltage smoothing capacitor 25 are connected via a serial resistor 28a of R. The voltage compensation capacitor 26 satisfies the relation RCnT/2, when the allowed voltage drop width VS is 1/n of VL, and the resistor 28a are used.
