Abstract

The invention relates to an S<4>R-type power supply control device. The invention aims to solve the problems of a traditional power supply control device that the performance is poor, the weight is high and the size is large. Triangular wave signals with certain frequency are generated by a triangular wave generating circuit of the S<4>R-type power supply control device. A first voltage signal sent by a solar cell array is received by a shunting control circuit; the first voltage signal and a reference voltage signal are compared to generate a second voltage signal; and the second voltage signal and a first triangular wave signal generated by the triangular wave generating circuit are compared to generate a first PWM (pulse-width modulation) signal. A third voltage signal generated by a lithium ion battery is received by a charge control circuit; the third voltage signal and the reference voltage signal are compared to generate a fourth voltage signal; and the fourth voltage signal and a second triangular wave signal generated by the triangular wave generating circuit are compared to generate a PWM signal. A first switching signal or a second switching signal as well as a third switching signal or a fourth switching signal are generated by a logic control circuit. The S<4>R-type power supply control device is suitable for the field of control.

Description

technical field [0001] The invention relates to a power control device, in particular to a S 4 R type power control device. Background technique [0002] As a key technology of the satellite platform, the technical level of the power control device affects and restricts the development level of the satellite, and its performance, working life, weight and price have a significant impact on the overall design of the satellite. Due to the characteristics of high energy density, wide temperature range, low self-discharge rate, no memory effect, long charge and discharge life, and no pollution, lithium-ion batteries have become a new generation of energy storage power for space, which is very suitable for the development of space power. At the same time, in recent years, satellites have problems of low performance, heavy weight and large volume for power supply control devices. Contents of the invention [0003] The present invention proposes a S 4 R type power control devic...
