Abstract

The invention provides a dual supersatellite platform maglev PCB ground wire connection system, including an isolated power supply, a reference source circuit, a digital logic component, a communication chip, a digital / analog conversion circuit, an analog / digital conversion circuit, a maglev power drive circuit, an analog ground plane and digital ground plane, the isolated power supply includes primary ground and secondary ground, the digital / analog conversion circuit and analog / digital conversion circuit both include analog ground and digital ground, and the reference source circuit ground wire, digital ground Both the analog ground of the analog / analog conversion circuit and the analog ground of the analog / digital conversion circuit are connected to the analog ground plane. The present invention eliminates the interference on the ground wire between the maglev power driving circuits, eliminates the interference of the maglev power driving circuit on the digital / analog conversion circuit, the analog / digital conversion circuit and the reference source circuit, and eliminates the digital logic components and communication chips Interference to the magnetic levitation power drive circuit, digital / analog conversion circuit, analog / digital conversion circuit and reference source circuit.

Description

Technical field [0001] The present invention relates to the field of satellite circuit wiring, and in particular, to a two-super-satellite platform magnetic PCB ground connection system, in particular a double super-satellite platform magnetic floating multi-circuit drive PCB ground connection system. Background technique [0002] Double super-satellite technology structure divides the satellite into load bin and service bin, and the two warehouse uses a magnetic floating work coil and a permanent magnet connection. The adjustment of the load bin posture is added to the magnetic floating moving coil, and the current generates in the magnetic field. Force to adjust the gesture. Double Super Satellite Platform Magnetic Floating Multiplexing is composed of an isolation power source, maglev power drive, a reference source circuit, a digital / analog conversion circuit, analog / digital conversion circuit, a digital logic component, and a communication chip. [0003] The Patent Docume...
