Introduction

In the RMVC 5100 converter, the medium voltage output isconstructed by connecting the outputs of single-phase
low-voltage IGBT-based inverters in series, with an equal number per phase. Each individual single-phase inverter power module is powered by an internal rectifier, itself supplied from separate phase-displaced secondary
windings of the integrated transformer. An inherent feature of this technology is that a high pulse number rectifier is created resulting in a significant reduction of input current harmonic distortion. In the example shown below for a 6kV output, the diode rectifier is 30-pulse. The input Power Factor is also high at a minimum of 0.95 regardless of speed and power. The PWM switching strategy ensures that sinusoidal current is supplied to the motor. The low levels of harmonic current in the motor ensure that both motor heating and shaft torque pulsations transmitted to the coupling and load are minimised. Use of the multi-level PWM topology also results in areduced size of voltage steps imposed on to the motor and cable insulation systems compared to 2 or 3-level inverters.The dV/dt is less than 1,000V/μs.
