Battery Charge Regulator (BCR)
- Fabrication Responsibility:
- Andras Gschwindt, HA5WH
- 3x 270x200
- Average Power Dissipation:
- 20 Watts each
The BCR modules are the elctronic parts of the power system on Phase 3-D
satellite. The MPP of solar array will be about 630 W (BCR1/130W, BCR2 and
BCR3/250W). Maximal power loss 23 W/modul (minimal efficiency 92,4% /modul).
The BCR2 and BCR3 contains the 10V-C1 and 10V-C2 power supplies. They work in
hot redundancy. The modules are controlled by onboard computer (solar array and
battery reference signals). Modules give voltage, current and temperature
telemetry signals. The BCR1 modul has an unbilical input.
