Development of low voltage 2 level IGBT inverter and converter for industrial applications

This paper presents a new IGBT based AC drive inverter and its DC source converter, which were developed for industrial applications. AC drive inverter provides some benefits to customer, very large capacity for an induction motor, a compact footprint and a secured safety stop sequence which is compliant with ISO/IEC functional safety standard. And DC source converter to supply DC input power to AC drive system also provides some benefits as same as AC drive inverter. In addition, it is expected that new PWM control "Instantaneous Current Control PWM (IccPWM)" can improve performance to suppress a harmful harmonics against other surrounding devices and provide a simple harmonic filter to comply with IEEE-519 harmonic limits.
