Back-up power supply 230V/50Hz/300VA with a battery supply 12V
 Snítilý, David ; Patočka, Miroslav (referee) ; Vorel, Pavel (advisor)
The aim of this project is to describe, design and create a converter from 12V DC to 230 VRMS. The power of this device is about 500W. The device consists of two main converters. The first one is step-up DC/DC converter and the other is DC/AC inverter. Step-up converter is designed as a resonant converter. It is useful for pushing down losses in semiconductors and inceasing efficiency. The inverter is changing DC voltage from the first converter to AC voltage. Control of this device is realized with DSP Motorola. This device should be used mainly for supply common devices up to 500W. Main usage is planed in a car or to another place where is not posible to connect some device to plug.
