Abstract

Plasma Wave Complex is a scientific instrumentation for wave parameters measurements in the ISS environment, and is implemented in the OBSTANOVKA experiment on board of Russian segment of ISS. The device Spacecraft Potential monitor „DP-1“and „DP-2“(one part of Plasma-Wave Complex) was developed in IKI BAS and measured the potential of the hull no more than 3 m from the surface of the ISS at range +/–200 V; 0to 500 Hz. There are block and functional diagrams of the "DP" and the secondary power supply system, designed to supply the measuring probe, analogue and digital circuit boards. The secondary power supply system for the device „DP-1“and „DP-2“is discussed herein detail.
