Abstract:
A very major role is played by DC-DC converters in the sphere of industries as well as in applications that are used in everyday life. It is necessary to have DC-DC converters in order to charge batteries that have a low voltage and are coupled to an uninterrupted power source (UPS).
Batteries require a low voltage, and the voltage that is available at the source must be step-down to the level of voltage that is required at the point of utility (PoU). When it comes to the design of DC-DC converters, keeping the circuit as simple and efficient as possible is of utmost importance.
Buck converters are able to produce voltage at the needed level, and their operation is fairly straightforward. However, the higher losses in diodes can be addressed by employing a synchronous Buck converter. Buck converters are mostly used for applications involving surge protection (UPS).
In a Buck converter, the diode conduction losses can be reduced to a minimum by the utilization of synchronous Buck converter, which ultimately results in an increase in the converter’s efficiency. A Synchronous Buck converter is going to be utilized in this article in order to charge the batteries of the UPS.
The modeling of a synchronous Buck converter for use in UPS applications was carried out in this article, and the results of that modeling were achieved through the use of Matlab/Simulink. It was also possible to develop a prototype of the hardware, and the findings of the hardware were also shown.
