The use of AC electric machines in the industry has generated the need of using high performance DC controllers or solid state converters. In order to satisfy said demand, novel and improved semiconductors and control algorithms have been created, the same allow higher powers to be handled, which are more efficient, since they use the nature of a direct converter to transform AC into DC as the matrix converter. In this case, a three-phase rectifying system is designed based on a synchronous rectification, since it uses an integrated circuit conceived for applications of a very low power, known as IR1167 (Smart Rectifier). This implementation uses the natural characteristics of MOSDETs for rectifying the voltage in an efficient manner. The invention may be used with any power supply regardless of the source, and supply a charge which demands the same a considerable amount of current, thereby the invention being flexible to be implemented to any system. |
