Array pulse load power supply circuit and control method thereof

Abstract

The invention provides an array pulse load power supply circuit and a control method thereof. The power supply circuit comprises an input offset module, a storage battery, n isolated DC-DC modules, noutput offset modules and n pulse loads; positive poles and negative poles of all the output offset modules are respectively connected with the positive pole and the negative pole of the storage battery, positive poles and negative poles of input ends of all the isolated DC-DC modules are respectively connected with the positive pole and the negative pole of the storage battery, positive poles andnegative poles of output ends of all the isolated DC-DC modules are respectively connected with positive poles and negative poles of the corresponding pulse loads, and positive poles and negative poles of all the output offset modules are respectively connected with positive poles and negative poles which are output by the corresponding isolated DC-DC modules. The circuit can improve the power supply quality of pulse load equipment and reliability of the power supply storage battery and prolongs the service life of the storage battery, the response speed is superior to that of a device whichadopts the same device to achieve charge-discharge control, the response speed is superior to that of simple linear control, and the circuit can completely compensate for the input current impact on the power supply storage battery.

Description

technical field [0001] The invention relates to an array pulse load power supply circuit and a control method thereof. Background technique [0002] In aerospace vehicles, some equipment with pulse load characteristics are often carried, and the pulse load power supply is a device used to supply power to equipment with pulse load characteristics. The instantaneous peak power of this type of equipment is very high, but the average power is very low, and the difference between the two can be several times or dozens of times. If a primary power supply such as a storage battery or a generator is selected with the highest instantaneous power, the volume and weight of the primary power supply will be too large, exceeding the limit that the aerospace vehicle can bear. Therefore, it is necessary to add a corresponding special secondary power supply between the primary power supply and the pulse load to reduce the impact of the pulse load equipment on the primary power supply, and m...
