System of simulation and control of a spacecraft onboard equipment power supply


  • complete simulation of external power supply from solar panels: mathematical model of nonlinear current-voltage characteristic with time synchronization is implemented
  • complete simulation of on-board storage batteries based on modular high-dynamic two-quadrant special power supply sources
  • simulation of performance characteristics  range, open circuit, short circuit inside a chemical element, group of elements, cell battery

System composition

  • mobile industrial design under the control of a single software platform. This concept allows quick changing both the physical parameters of each power supply simulation output (I—V characteristic, voltage, current, power) and the total number of channels.
  • based on modular devices of the LXI standard

Software platform of the system

Windows operating system. Special software designed by IRZ
