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
