AI Technical Summary

Technical Problem

When the existing driving force-taking generator is in the parking state of the vehicle or in the low-speed driving state, the low input voltage leads to large heat loss of power conversion, affecting working efficiency, and cannot effectively meet the power consumption needs of on-board power equipment.

Method used

By controlling the working state of the input and cutting winding, the lower limit of the generator output voltage is increased, and the output voltage range is compressed, so that the boost and buck conversion circuit can obtain a large input voltage in the low-speed state, reduce heat loss, improve power conversion efficiency, and maintain the output power stability in the high-speed state.

Benefits of technology

It effectively improves the lower limit of the generator output voltage, reduces the heat loss of power conversion, improves the power conversion efficiency, and ensures that the output power can meet the power consumption needs of various vehicle-mounted electrical equipment.

Abstract

The invention provides a driving power take-off power generation control method and driving power take-off power generation equipment, and relates to the technical field of vehicle driving power generation. Whether the actual output voltage data of the fixed winding meets the rated generation power requirement of external power transmission of the buck-boost conversion circuit is detected, and the switching winding is controlled to cooperate with the fixed winding to transmit power to the buck-boost conversion circuit according to the detection result. Therefore, the buck-boost conversion circuit can obtain large input voltage when the vehicle is in a parking state or a low-speed driving state, so that the electric power conversion heat loss of the buck-boost conversion circuit in the corresponding vehicle state is reduced, the electric power conversion efficiency is improved, it is guaranteed that the corresponding output electric energy power is improved, and the service life of the vehicle is prolonged. Or the fixed winding is controlled to independently transmit power to the buck-boost conversion circuit according to the detection result, so that the corresponding output electric energy power is stabilized at the rated power generation power as much as possible in the high-speed driving state, and the corresponding output electric energy power range is ensured to meet the power utilization requirements of various vehicle-mounted electric equipment as much as possible.
