| Abstract |
Three phase bidirectional rectifiers or Voltage Source Recifiers (VSR) among other alternatives, offer several advantages over line conmutated rectifiers. Advantages include displacement power factor control, reduced line current harmonic distortion and ac four-quadrant operation can be obtained. On its dc side a dc-link unidirectional voltage is obtained and bidirectional power transfer capability is possible by reversing the flow direction of the dc-link current. This paper presents the analysis and design procedure for the control loop of a three phase bidirectional rectifier. Experimental results from a 1.5 kW VSR show the feasibility of the design procedure. The complete mathematical model of the rectifier in the synchronous reference frame has been programmed on a DSP. The actual currents and output voltage are acquired through the on-chip A/D converters. A space vector modulation has been implemented by using the PWM unit, a PLL has been implemented by using a look-up table and two capture inputs. |
