abstract = "This article discusses the development of a power system, capable
of supplying the entire energy demand of the attitude control
subsystem, communication, data processing and payload of the
CubeSat, Escola de Engenharia MauŽas project. The power system
developed is responsible for generating, distribution and control
of the entire energy flow of the CubeSat MauŽa. The energy
generated by high efficiency aerospace photocells, endowed with
the triple junction technology is stored in Ion-Lithium batteries.
The distribution of energy is made by three levels of stabilized
voltages and regulated in 3.3V, 5V, 12V and there is a unregulated
level supplied directly from the battery. In case of failure, a
set of redundant power supplies are able to take any of the
regulated voltages levels. All control of the power system is
performed by a microcontroller, which collects and analyzes data,
such as temperature, voltage and current to determine whether the
system power will come from major sources or from redundant ones.
Through a CAN network, the microcontroller transmits telemetry
information to a Data Processing Unit (DPU), which takes more
complex decisions involving all the CubeSat subsystems.",
