Title:
POWER DEVICE WHICH IMPROVES TRANSIENT RESPONSE TO CHANGE IN LOAD
Document Type and Number:
Japanese Patent JP3907016
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To prevent a transient response in the main output during voltage drop by supplying current to a variable load by a supply means and functionally connecting to the supply means an additional supply means for supplying additional current to the load in response to the change in the load.
SOLUTION: Current is supplied to a variable load by a main voltage source 10 as a supply means. In order to supply additional current to the variable load in respond to the change in the load, an additional supply means is functionally connected to the main voltage source 10. The additional supply means consists of an additional voltage source 11, a charge accumulating means such as a bulk capacitor 12, and a current generator 13 to supply current of a magnitude I which changes as a function of a differential error signal E to be supplied to an error amplifier 16. By this method, a transient response in the main output during voltage drop can be prevented.
