Multi-Kilowatt low voltage DC power conditioning for active satellite SAR antennas.
Active antennas are equipped with hundreds of transmit/receive modules to be supplied with DC voltages between -5 and +10 V.
A central DC to AC inverter generates a 115 V AC bus including redundancy. AC power is distributed to the antenna panels. Panel Power Conditioners re-convert AC to low voltage DC.
Additional features are S/C bus protection, failure detection and isolation, redundancy switching, housekeeping etc.
