Abstract
Systems and methods for processing power provided to downhole electrical systems such as electric submersible pump motors to increase the power factor of the supplied power. In one embodiment, a system comprises a downhole motor and a power factor corrector. The motor may be coupled to drive an electric submersible pump. The power factor corrector is configured to receive input power, process the received input power using one or more capacitive electrical components and thereby impart a capacitive phase shift between the voltage and the current of the received input power. The processed output power is provided to the downhole motor, which consumes the processed output power with a power factor which is greater than it would have been in the absence of the correction.
