Using High-Control-Bandwidth FPGA and SiC Inverters to Enhance High-Frequency Injection Sensorless Control in Interior Permanent Magnet Synchronous Machine
Abstract
A high-frequency injection (HFI) sensorless control for interior permanent magnet synchronous motors with enhanced precision and widened speed range is proposed in this paper. The injection frequency reaches up to 2 kHz under a 50~100 kHz silicon carbide (SiC)-based three-phase inverter. In addition to the high switching frequency, the field-programmable gate array (FPGA) is utilized to achieve high control bandwidth (>200 kHz) when …
