One-Cycle Control Technique Applied to PWM Three-Phase Rectifier with Power Factor Correction
Power Quality, Controlled Rectifier, One Cycle Control
In this work, the one-cycle control technique will be used to control a three-phase 1kVA rectifier based on the boost topology without the use of voltage sensors in the system coupling point. The implementation will be digital using DSP TMS 320F28335 from Texas Instruments. The purpose of the proposed implementation is to obtain at the rectifier input a current drawn from the sine source and with a power factor as close as possible to the unit while the rectifier output is controlled at a fixed voltage value. To evaluate the proposed system, simulations were performed using the PSIM software and preliminary results verified in a laboratory prototype.
