APPARATUS FOR RECOGNIZING AND ELIMINATING INFLUENCE OF GENERATION VOLTAGE RIPPLE NOISE IN VOLTAGE CONTROLLING DEVICE FOR VEHICLE ALTERNATOR

摘要

The present invention relates to a voltage regulation device capable of stably operating the generator by sampling the battery input voltage according to the output phase of the generator included in the vehicle. The voltage regulating device according to an embodiment of the present invention includes a generator that performs a power generation operation when an engine of a vehicle is driven to output a power generation voltage, a rectifying part that rectifies the power generation voltage output from the generator, and the power generated by the rectification part It includes a battery that charges a voltage and supplies a load operating voltage that operates the load, and a voltage regulator that adjusts the generator voltage output by the generator based on the input voltage of the sampled battery according to the phase of the generator voltage output from the generator. .
