Uninterruptible power supply for Robotics
 Kejík, Petr ; Ligocki, Adam (referee) ; Burian, František (advisor)
This Bachelor thesis deals with the design and construction of a DC power supply unit with the possibility of battery backup power. The device in intended as an uninterruptible power supply for robotic devices. Thanks to its modularity it can also be used to power other small appliances and it can be easily expanded with more functions. In the designed configuration, the device contains two identical output modules, which together provide four independent power outputs. The power output voltages are adjustable in the range of 3–20 V, with a maximum considered continues current of 6 A. Digital control of modules and monitoring of critical parameters is procured through two Atmel ATmega32U4 microcontrollers placed on separate main board. Configuration and communication with the device it self is done via a local user interface (display and keyboard) and USB port (virtual seriál interface). Main power supply is provided by means of an external commercial DC power source producing voltage in the range of 30–38 V. Backup operation is secured from a 24V lead-acid battery, which is also recharged in normal conditions
