Medium Voltage Drive Selection Guide
Selecting a suitable medium voltage drive (MV VFD) is one of the most critical decisions for modern heavy industrial renovation and new project construction. Unlike low-voltage variable frequency drives used for general machinery, medium voltage drives operate at 2.3kV to 13.8kV, supporting high-power equipment from hundreds of kilowatts to tens of megawatts. They are widely…
Three-level Inverter Working Principle
A three-level inverter is also known as a Neutral Point Clamped (NPC) inverter. It acts as the core power conversion unit for modern medium and high-voltage VFD systems. Traditional two-level inverters only output two voltage states. In contrast, standard three-level inverters produce three stable levels: +VDC/2, 0, and -VDC/2. This unique structure delivers better power…
