[0006] 1) The design of the control circuit of the charge regulator is complex, and there are certain requirements for the characteristics of the topology
In addition to the constant current and constant voltage loops that meet the charging requirements of the battery, the charging regulator also needs to set a constant voltage loop to control the bus voltage in the charging domain, which makes the design of the control circuit more complicated.

Embodiment Construction
[0021] The following is attached Figure 1-5 A new control strategy of the spacecraft charging regulator proposed by the present invention is further described in detail. It should be noted that the drawings are all in simplified form and with imprecise ratios, only to clearly and clearly describe the implementation method and purpose of the present invention.
[0022] The core idea of the present invention is to cancel the constant voltage loop for stabilizing the bus voltage of the charging regulator, and adopt the constant current loop for equalizing the power with the reference automatic adjustment. That is, when the battery does not reach the set constant voltage value, when the spacecraft has sufficient energy in the light period, the charging regulator will charge the battery with a constant current based on the set charging current reference; when the output power of the solar array is less than the load power When it is the sum of the charging power set by the batt...

The invention provides a novel spacecraft charging regulator control method. When the energy of a spacecraft is sufficient in an illumination period, acharging regulator charges a storage battery according to a set charging current reference; and when the output power of a solar array is lower than the sum of the load power and the set charging power of the storage battery, the charging regulator automatically regulates the charging current reference according to the magnitude of a signal of a bus voltage main error amplifier (MEA), so that the function of automatically regulating the charging current of the storage battery is realized, and the purpose of power balance is achieved. Compared with a traditional charging regulator control method, the charging regulator control method of the invention has the advantages that the charging power is adjusted by automatically adjusting the charging current reference signal under the working condition of insufficient energy, a loop for stabilizing the bus voltage does not need to be independently arranged in the charging regulator, and design of a charging regulator control circuit is greatly simplified.
Description
technical field [0001] The invention relates to the field of space power supplies, and relates to a control method for a spacecraft charging regulator suitable for sufficient light conditions. Background technique [0002] With the development of a new generation of large geostationary earth orbit (Geostationary Earth Orbit, GEO) satellites, the power required by satellites continues to increase, which puts forward higher requirements for the design of satellite power systems. and expandability. Therefore, it is of practical value to optimize the charging regulator, one of the important components of the satellite power system. [0003] Most spacecraft power systems still use solar array-battery power systems. During the light period, the load demand is given priority. Under the premise of meeting the load power and battery pack charging demand, the extra energy is shunted and dissipated through the sequential shunt; when the load / bus demand increases, the shunt is reduced...
