Implementation Issues of a Fuzzy-Logic-Based Three-Phase Active Rectifier Employing only Voltage Sensors
No full textSwitch-mode rectifiers are becoming more and more
interesting in those applications where bidirectional power flow,
power-factor correction, and electromagnetic interference re-
duction are required. Typical active rectifiers include current or
voltage sensors, however, in order to obtain low-cost systems, their
number should be reduced. In this paper, a current-sensorless
active rectifier with feedforward fuzzy logic control is presented
and discussed. The mathematical description of the system and the
design of the fuzzy logic controller are introduced and analyzed;
moreover the implementation on a SH7047 microcontroller is
presented with emphasis on the most significant implementation
issues. Experimental results are reported and discussed

No full textSwitch mode rectifiers are becoming more and more interesting in those applications where bidirectional power flow, power factor correction and EMI reduction are required. However, in order to obtain low cost systems, the number of sensors should be reduced. Therefore, in this paper, a current-sensorless feed-forward fuzzy logic controller is presented and discussed. The mathematical description of the system and the design of the fuzzy-logic controller are introduced and analysed, then its implementation on a general-purpose microcontroller and experimental results are reported and discussed
