Abstract

The invention provides a high-power-density high-pulse load power supply platform which is based on an integrated power supply controller bus framework. The platform includes an integrated power supply controller, a solar cell array, a storage battery, a bus, an MPPT module, a wired energy transmission module and a wireless energy transmission module, a load and a super-capacitor charging / discharging CDDR module, the integrated power supply controller is realized by adopting a three-port converter, the three-port converter is connected with the solar cell array, a storage battery and a bus, the MPPT module is integrated in the integrated power supply controller; an 'Energy LAN' consisting of multiple solar array-battery DC power supply systems PBPS is connected with the bus via a wired grid-connected controller; the CDDR module is arranged between the online and pulsed load and used for charging and discharging the super capacitor through a bidirectional boosting and voltage reducing module, so that a small average power is input, and the larger peak pulse power is output.

Description

technical field [0001] The invention relates to the technical field of power supply control, in particular to a high power density and high pulse load power supply platform. Background technique [0002] Under complex space conditions and multi-task requirements, in order to meet the normal work of different types of payloads, higher requirements are put forward for satellite power controllers. In particular, repetitive pulse loads require the input of very high energy, ie, pulse or burst energy, for a very short period of time. The traditional method needs to be realized by continuously increasing the power of the power controller of the satellite platform. The weight and volume increase with the increase of power, the power density is low, and the launch cost is high. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a high power density high pulse load power supply platform, and the present invention is s...
