Abstract:
An electric submersible pump (ESP) variable speed drive (VSD) controller is described. A VSD control system includes a pump assembly including an induction motor operatively coupled to a pump, a power cable and a transformer electrically coupled between the induction motor and a VSD controller that controls a speed of the induction motor, the VSD controller including a converter section that sends a direct current (DC), a DC link including a DC smoothing capacitor that smooths the DC, an inverter that converts the smoothed DC to a pulse width modulated (PWM) output voltage, the inverter including at least one silicon carbide (SiC) power semiconductor module, and a PWM filter that filters the PWM output voltage to produce near sinusoidal voltages, the PWM filter including inductors, and the PWM filter sending voltage to the transformer.

Claim (Index 15):
The VSD control system of  claim 12 , wherein each of the at least one SiC power semiconductor modules comprises at least one SiC IGBT device.
