Title:
CHARGER FOR CAPACITOR STORAGE POWER SUPPLY
Document Type and Number:
Japanese Patent JP2007221933
Kind Code:
A
Abstract:

To achieve a function equivalent to a power limiter function of a charger by a simple constitution and enable reduction in the power consumption of a parallel monitor and the size of a capacitor storage power supply.

A charger for a capacitor storage power supply is configured to control a charging current for the capacitor storage power supply 7 that stores power in an electric double layer capacitor 71 and charge the power supply. This charger is provided with a signal generating means 2 that compares a current reference value for reducing a charging current I in inverse proportion to increase in the charging voltage Vc of the capacitor storage power supply 7 with the charging current I, and generates an error amplification signal. Pulse width modulation is carried out from a charging power supply 5 by a pulse width modulation means 4.
