Diseño y control de un convertidor cc/cc buck cuadrático

Abstract

Currently, the world is changing constantly and this imply to think about solutions to contribute to a better world, in order to do so, the need must be dealt to bring eviromental & green solutions inmediately deploying renewable power supplies with efficient and reliable systems decreasing the uso of non renewable power supplies which are enviromental pollutants.

This graduation project takes the values of the power buses supplies around 380 and 400 volts, being simulated by a similar power source changing them into 48 volts output. For this purpose a quadratic buck down converter DC which delivers 200w power will be implemented, using a PI type 3 control system allowing to maintain the stability during resistivity changes.

Considerinh that there are already some systems on the market with some similarities, those provide a mainstream control system which do not furnish good behaviour around the operating point, having slower responses within the wave forms with significant disruption, being susceptible to parameter changes.

The scope for this project is to deliver a prototype to charge electric vehicles the latter being implemented on charge stations around 10kw and 20kw. Besides yield a solution to the micro networks on dwellings or bussineses to achieve an autonomous sustainability of themselfs.
