Harmony VFD Family Features
The Harmony VFD families consist of four core design configurations, where they are
functionally identical and share a common controller. These four design configurations are
targeted at distinct output power configurations with little overlap between the frame sizes.
These drive families are summarized as follows:

Evolution
Historic Milestones:
1994: World’s 1st fully integrated voltage source inverter (VSI) medium voltage motor
drive using IGBTs that meet IEEE 519 for input current distortion and NEMA/IEC
for motor HVF (without using output step-up transformers or line/load filters).
1995: 1st IGBT-based 6.6 kV drive without an output transformer.
1996: 1st IGBT-based drive above 10000 Hp (7500 kW).
1998: Introduction of ProToPSTM and 500th Perfect Harmony drive installed.
1999: Introduction of process-transparent cell bypass ("fast bypass") capability and
neutral point shift.
2000: 1st VSI drive to operate a medium voltage synchronous motor.
2001: 1000th Perfect harmony drive installed.
2002: 1500th Perfect Harmony drive installed.
2003: 1st High Voltage 13.8 kV drive capable of operating motors from 4000 to
90000 Hp connected directly to 13.8 kV source.
2004: Built largest PWM drive, 80000 Hp.
2006: Introduction of smallest footprint medium voltage VFD, GenIV "MicroHarmony".
