Abstract: A power conversion system is disclosed that provides multiphase power, including phase voltages for each phase of the multiphase power. The system comprises a plurality of inverters that generate PWM output voltages based on PWM control signals. A plurality of inductive components is configured to receive the PWM output voltages to generate the phase voltages. The PWM output voltages cause circulating current flows through the inductive components. A voltage controller is employed that is responsive to the phase voltages to generate voltage modulation signals corresponding to the phase voltages. A plurality of current sharing channels are respectively associated with each of the plurality of inductive components and are configured generate current sharing modulation signals in response to the circulating current flows. The PWM control signals are generated based on modulation signals obtained by combining the current sharing modulation signals and voltage modulation signals.

Patent CA-2840740-A1 (CA)
Title: Improved pump down tool
Inventor: FRAZIER W LYNN
IPC: E21B23/10
Filed: 2014-01-27
Abstract: A pump down tool includes a resilient cup on the tool exterior to minimize leakage of pumped fluid around the outside of the tool when the tool is pumped into a well. The resilient cup is concave toward an upper end of the tool so it expands upon application of pressure to pump the tool into the well.  The resilient cup is capable of expanding to a diameter sealing against the inside of the casing string. A fluid bypass around the resilient cup allows a fraction of the pumped fluid to stir up any proppant lying in the path of the tool thereby allowing the tool to move through a horizontal well without having to plow through the proppant.
