Abstract

The invention discloses an isolated satellite power source controller, belonging to the technical field of satellite power source controllers. The isolated satellite power source controller is characterized by at least comprising: a solar cell power regulator connected with a solar cell array; a bus capacitor connected with a load; and an isolated storage battery charging and discharging regulator and a pulsating load, which are connected with a storage battery pack, wherein the positive electrode of the solar cell power regulator is connected with the negative electrode of the solar cell power regulator through the bus capacitor, the positive electrode of the isolated storage battery charging and discharging regulator is connected with the positive electrode of the solar cell power regulator, and the negative electrode of the isolated storage battery charging and discharging regulator is connected with the negative electrode of the solar cell power regulator. Due to the fact that a circuit of the isolated storage battery charging and discharging regulator is adopted, the load adaptability of the power source controller can be remarkably enhanced, and bus voltage quality is improved.

Description

technical field [0001] The invention belongs to the technical field of satellite power controllers, and in particular relates to an isolated satellite power controller. Background technique [0002] In the design of traditional satellite power controllers, in order to meet the power supply requirements of pulsating loads, the pulsating loads are usually directly connected to both ends of the battery pack, and the battery packs provide short-term high-power pulse power; for stable platform loads, connect To both ends of the bus capacitor, powered by the DC bus. Power supply block diagram as figure 1 As shown, the power controller is a non-isolated form, including a solar battery power regulator, a battery charge and discharge regulator, and a bus capacitor. The solar battery power regulator adjusts the output power of the solar battery array to generate a stable DC bus; the battery charge and discharge regulator charges the battery pack during the light period to ensure the...
