PowerFlex 7000 Rectifier Design Selection Application Note

This application note compares three front-end rectifier options for the PowerFlex 7000 Medium Voltage Drive: a 6-pulse thyristor-controlled rectifier with passive-tuned harmonic filters, an 18-pulse phase-controlled rectifier, and a Pulse-Width Modulation (PWM) active rectifier. It discusses their respective advantages regarding harmonic compliance (IEEE-519), power factor, efficiency, footprint, cost, and suitability for different motor and plant conditions.
