Power converting and filtering device for spaceborne wireless transceiver

Abstract

The invention discloses a power converting and filtering device for a spaceborne wireless transceiver. The power converting and filtering device comprises a primary power protection module, a primarypower filtering module, a secondary power conversion module, a secondary power filtering module and a tertiary power conversion module which are connected in sequence, wherein a primary power supply sequentially passes through the primary power protection module and the primary power filtering module, generates s paths of secondary power voltage through the secondary power conversion module; the spaths of secondary power voltage enter the secondary power filtering module; the secondary power filtering module outputs n paths of low-noise secondary power voltage and m paths of common secondarypower voltage, wherein p paths of low-noise secondary power supplies and q paths of common secondary power supplies enter the tertiary power conversion module, and p paths of low-noise tertiary powersupplies and q paths of common tertiary power supplies are output; the low-noise secondary power supplies and the low-noise tertiary power supplies are used as the power supplies provided for a low-noise circuit or a linear circuit; and the common secondary power supplies and the common tertiary power supplies are used as the power supplies provided for the circuit which is insensitive to power supply noise.

Description

technical field [0001] The invention relates to the field of satellite power supply systems, in particular to a power conversion and filtering device for a satellite-borne wireless transceiver. Background technique [0002] The satellite power system is used to provide working power for satellite payloads and satellite platform loads. Satellite platforms are equipped with a large number of wireless transceiver equipment, such as measurement and control transponders, data communication machines, navigation receivers, data transmission transmitters, etc., which require special power conversion devices to solve the following problems: [0003] 1. Some wireless transceiver equipment has high requirements on the sensitivity of the received signal and the spectral purity of the transmitted signal, so it is very sensitive to power supply noise interference, and the requirements for power supply noise suppression are much higher than that of general electronic equipment.
