Abstract

The article describes solid-state relays, a voltage regulator and a power management network which are employed in a balloon borne experiment. Electronics borne on a balloon experiment become more and more complicated, and the number of the batteries borne on the balloon increases accordingly. The solid-state relays are introduced to facilitate control and management of a large number of the batteries. Turn-on resistance of the solid-state relay is kept within a prescribed allowance. The solid-state relays control power supplies from the batteries. The voltage regulator features both a low dropout voltage and a large output current capacity. The low dropout voltage extends the duration while the battery supplies enough voltage for proper operation of the regulator. The solid-state relays and the voltage regulator are kept under the control of the power management network. The network is composed of relay nodes and a command node. The solid-state relays and the voltage regulator are controlled by the relay nodes. The command node receives commands sent from a ground station and makes it possible to turn on and off the electronics remotely from the ground station.
