A power system for a reactive gas generator can include a direct three phase inverter. A resonant tank can further be included to receive a square wave output of the direct three phase inverter and provide a sine wave output. The power system can include an inverter controller that turns on and off selected switches of the direct three phase inverter based on states of the three phases of a three phase AC power supply, where a switch is turned on with an adaptive ON time and a modulated OFF time depending on a desired output power.

Systems and methods for conveying power and data between surface equipment, an ESP and one or more remote tools while requiring a reduced number of penetrations through a tubing hanger. In one embodiment, a primary cable carries power and data between surface equipment and the ESP. A separate secondary cable is coupled between the ESP and the remote tools. The ESP receives power from the surface equipment via the primary cable, and the remote tools receive power from the ESP via the secondary cable. A step-down transformer in the ESP transforms power to reduced-voltage AC power, or a rectifier produces rectified DC power which is provided to the remote tools via the secondary cable. A transceiver in the ESP communicates data between the surface equipment and the remote tools. Data and power for the ESP and remote tools are conveyed through a single common penetration in a tubing hanger.
