    Abstract: A switch assembly includes one or more solid state semiconductor switches configured to be disposed within a downhole pipe assembly. The one or more switches are configured to operate in a closed state to conduct electric current supplied by a power source disposed above a surface to pumps disposed beneath the surface to cause the pumps to extract a resource from beneath the surface via the pipe assembly. The one or more switches also are configured to operate in an open state to stop conducting the electric current from the power source to the pumps.

    Abstract: A power converter includes a first bus converter for converting a first direct current (DC) bus voltage into a first high frequency alternating current (AC) voltage and a second bus converter for converting a second high frequency AC voltage into a second DC bus voltage. A resonant circuit couples the first bus converter and the second bus converter. Further, a controller provides switching signals to the first bus converter and the second bus converter to operate the power converter in a soft switching mode. The controller includes a voltage detection circuit connected across at least one switching device of the power converter to detect a device voltage across the at least one switching device and a counter to count a number of hard switching detection pulses of the hard switching pulse signal detector. The controller also includes a calculation module to update the number of hard switching detection pulses of the hard switching instances and to generate a new number of hard switching detection pulses and a comparator to compare the new number of hard switching detection pulses with a threshold value and to provide a control signal if the new number exceeds the threshold value.

    Abstract: A gate drive unit includes a charging device, a switch, and a timing module. The charging device is conductively coupled with an electrical energy source and a power switch between the electric energy source and the charging device. The switch closes to transfer electrical energy from the energy source to the charging device. The timing module is configured to close the switch to direct the electrical energy from the electrical energy source to the charging device for a designated charging time period in order to charge the charging device with the electrical energy while the power switch is in an OFF state. The timing module opens the switch to cause the electrical energy stored in the charging device to be transferred out of the charging device in the form of a trigger current that is conducted to a gate terminal of the power switch to activate the power switch to an ON state from the OFF state.

    Abstract: Power systems and methods are disclosed herein. The systems and methods use a switching system coupled with a power source and subterranean pumps for pumping a resource from beneath a surface of earth. A first capacitor is between a first switching device and a first transformer, and stores electric energy received from the first transformer to activate the first switching device. A bias capacitor is between the first capacitor and the first switching device, and receives a bias voltage via a second transformer. The bias capacitor applies the bias voltage to the first switching device to prevent the first switching device from activating unless a combination of the voltage received by the first switching device via the first transformer and the bias voltage is at least as large as the activation voltage of the first switching device.
