A Three-Phase Motor System with 1 kW Rating and Six-Step Inverter Control

A three-phase motor rated at 1 kW, operating at 500 Vdc with a speed of 3000 rpm, is powered by a six-step voltage inverter. The inverter utilizes a MOSFET bridge from the SimPowerSystems™ library, regulated by a speed controller that adjusts the DC bus voltage. The inverter gate signals are generated by decoding Hall effect sensor signals from the motor, implementing a dual-loop control strategy for speed synchronization and voltage regulation.
