Abstract

The authors describe the HS601 spacecraft battery discharge controller (BDC), a fully redundant 100 kHz boost converter which provides up to 2 kW at 50.5 VDC from a 32 cell battery (32-45 VDC). The converter is designed to be connected in parallel with a second unit to provide up to 4 kW to the spacecraft to the spacecraft bus during an eclipse. Because a single design must accommodate many different spacecraft configurations, the unit must operate properly over a wide range of battery voltage (24 to 48 VDC), load current, and load impedance. The HS601 achieves ultra-low output ripple voltage (<30 mvpp), low input ripple current (<10 mapp), and high efficiency (>90%) using a unique coupled inductor boost converter topology
