Patent ID: 8724354

Claim:
A multi-phase inverter control device, which is used to output voltages across at least one load that yields a continuous-time (CT) inverter output current signal (IOCS) in matrix and feeds a CT load-side inherent voltage signals (LIVS), comprising a discrete circuit receiving a CT inverter output current command signal (IOCCS), said CT IOCS and said CT LIVS, and converting them into a plurality of discrete-time (DT) signals; a multi-dimensional quantization circuit electrically connecting with said discrete circuit, receiving said DT signals, and calculating according to an MDFQCC (Multi-Dimensional Feedback Quantization Current Control) algorithm to obtain a DT inverter output voltage signal (IOVS) for determining a plurality of switching signals; a driver circuit electrically connecting with said multi-dimensional quantization circuit, receiving said switching signals, and converting said switching signals into a plurality of switch driving signals; and an inverter circuit electrically connecting said driver circuit and said load, and receiving said switch driving signals to drive said load, whereafter said load yields said CT IOCS and said CT LIVS to said discrete circuit; wherein said DT signals include a DT IOCCS, a DT IOCS, and a DT LIVS, and wherein said discrete circuit receives said CT IOCCS, said CT IOCS and said CT LIVS, and converts them into said DT IOCCS, said DT IOCS, and said DT LIVS, respectively.
