Coupled-Coil Inductor Inverters
Producing multilevel output voltage from just two fast-switching semiconductors by using a coupled inductor . This frees the inverter from dead-time and greatly reduces low-order harmonics . |
Competitive Advantage • More reliable – coupled inductor lowers the risk of DC-link shoot-through
• Cost-effective – fewer semiconductors are employed for three-level output
• Simpler control – no need to balance DC-link capacitor voltage under any condition
Impact • Improves efficiency and reliability
Successful Applications • Inverter-based five-phase permanent-magnet synchronous machine-drive system
Capabilities and Facilities • Advanced control platform with DSP and FPGA
